Cara menghitung berat besi beton (polos): Diameter x Diameter x Panjang x 0,006165 (diameter dalam satuan milimeter, pa

Cara menghitung berat besi beton (polos):
Diameter x Diameter x Panjang x 0,006165

(diameter dalam satuan milimeter, panjang dalam satuan meter)

0,006165 dari:

3,14 / 4  x 7854 / 1000000

3,14 adalah PI
4 (hitung volume tabung atau luas lingkaran) karena yang dikuadratkan diameter, maka dibagi 2 kuadart = 4
7854 adalah berat jenis baja (kg per meter kubik)
1000000 karena diameternya dalam milimeter ke meter kuadrat (1000 kuadrat)


.

Besi beton polos tidak bisa benar-benar bulat, karena proses rolling mill memang karakternya seperti itu. Besi (baja) bulat hasil dari mesin bubut saja, ada toleransinya, apalagi hasil penggilingan. Untuk itu, biasanya, untuk mendapatkan diameter besi beton, diukur beberapa kali, dan hasilnya dirata-rata.

Cara menghitung besi beton polos tersebut tidak berlaku untuk menghitung berat besi ulir (sirip). Diameter dalam besi beton ulir tidak bisa biasanya tidak persis sama untuk hasil pada ukuran tertentu, karena tebal dan kedalaman ulirnya tidak sama, tergantung pembuatan matrasnya (calibernya).

Untuk menghitung berat besi kotak (nako / virkan):

Diameter x Diameter x Panjang x 0,007854

Angka (nilai) 0,007854 adalah berat jenis baja (kg per meter kubik) dibagi 1000000 karena diameternya dalam milimeter ke meter kuadrat (1000 kuadrat)

WASHINGTON — During a training course on defending against knife attacks, a young Salt Lake City police officer asked a question: “How close can somebody get to me before I’m justified in using deadly force?”

Dennis Tueller, the instructor in that class more than three decades ago, decided to find out. In the fall of 1982, he performed a rudimentary series of tests and concluded that an armed attacker who bolted toward an officer could clear 21 feet in the time it took most officers to draw, aim and fire their weapon.

The next spring, Mr. Tueller published his findings in SWAT magazine and transformed police training in the United States. The “21-foot rule” became dogma. It has been taught in police academies around the country, accepted by courts and cited by officers to justify countless shootings, including recent episodes involving a homeless woodcarver in Seattle and a schizophrenic woman in San Francisco.

Now, amid the largest national debate over policing since the 1991 beating of Rodney King in Los Angeles, a small but vocal set of law enforcement officials are calling for a rethinking of the 21-foot rule and other axioms that have emphasized how to use force, not how to avoid it. Several big-city police departments are already re-examining when officers should chase people or draw their guns and when they should back away, wait or try to defuse the situation

Hockey is not exactly known as a city game, but played on roller skates, it once held sway as the sport of choice in many New York neighborhoods.

“City kids had no rinks, no ice, but they would do anything to play hockey,” said Edward Moffett, former director of the Long Island City Y.M.C.A. Roller Hockey League, in Queens, whose games were played in city playgrounds going back to the 1940s.

From the 1960s through the 1980s, the league had more than 60 teams, he said. Players included the Mullen brothers of Hell’s Kitchen and Dan Dorion of Astoria, Queens, who would later play on ice for the National Hockey League.

One street legend from the heyday of New York roller hockey was Craig Allen, who lived in the Woodside Houses projects and became one of the city’s hardest hitters and top scorers.

“Craig was a warrior, one of the best roller hockey players in the city in the ’70s,” said Dave Garmendia, 60, a retired New York police officer who grew up playing with Mr. Allen. “His teammates loved him and his opponents feared him.”

Young Craig took up hockey on the streets of Queens in the 1960s, playing pickup games between sewer covers, wearing steel-wheeled skates clamped onto school shoes and using a roll of electrical tape as the puck.

His skill and ferocity drew attention, Mr. Garmendia said, but so did his skin color. He was black, in a sport made up almost entirely by white players.

“Roller hockey was a white kid’s game, plain and simple, but Craig broke the color barrier,” Mr. Garmendia said. “We used to say Craig did more for race relations than the N.A.A.C.P.”

Mr. Allen went on to coach and referee roller hockey in New York before moving several years ago to South Carolina. But he continued to organize an annual alumni game at Dutch Kills Playground in Long Island City, the same site that held the local championship games.

The reunion this year was on Saturday, but Mr. Allen never made it. On April 26, just before boarding the bus to New York, he died of an asthma attack at age 61.

Word of his death spread rapidly among hundreds of his old hockey colleagues who resolved to continue with the event, now renamed the Craig Allen Memorial Roller Hockey Reunion.

The turnout on Saturday was the largest ever, with players pulling on their old equipment, choosing sides and taking once again to the rink of cracked blacktop with faded lines and circles. They wore no helmets, although one player wore a fedora.

Another, Vinnie Juliano, 77, of Long Island City, wore his hearing aids, along with his 50-year-old taped-up quads, or four-wheeled skates with a leather boot. Many players here never converted to in-line skates, and neither did Mr. Allen, whose photograph appeared on a poster hanging behind the players’ bench.

“I’m seeing people walking by wondering why all these rusty, grizzly old guys are here playing hockey,” one player, Tommy Dominguez, said. “We’re here for Craig, and let me tell you, these old guys still play hard.”

Everyone seemed to have a Craig Allen story, from his earliest teams at Public School 151 to the Bryant Rangers, the Woodside Wings, the Woodside Blues and more.

Mr. Allen, who became a yellow-cab driver, was always recruiting new talent. He gained the nickname Cabby for his habit of stopping at playgrounds all over the city to scout players.

Teams were organized around neighborhoods and churches, and often sponsored by local bars. Mr. Allen, for one, played for bars, including Garry Owen’s and on the Fiddler’s Green Jokers team in Inwood, Manhattan.

Play was tough and fights were frequent.

“We were basically street gangs on skates,” said Steve Rogg, 56, a mail clerk who grew up in Jackson Heights, Queens, and who on Saturday wore his Riedell Classic quads from 1972. “If another team caught up with you the night before a game, they tossed you a beating so you couldn’t play the next day.”

Mr. Garmendia said Mr. Allen’s skin color provoked many fights.

“When we’d go to some ignorant neighborhoods, a lot of players would use slurs,” Mr. Garmendia said, recalling a game in Ozone Park, Queens, where local fans parked motorcycles in a lineup next to the blacktop and taunted Mr. Allen. Mr. Garmendia said he checked a player into the motorcycles, “and the bikes went down like dominoes, which started a serious brawl.”

A group of fans at a game in Brooklyn once stuck a pole through the rink fence as Mr. Allen skated by and broke his jaw, Mr. Garmendia said, adding that carloads of reinforcements soon arrived to defend Mr. Allen.

And at another racially incited brawl, the police responded with six patrol cars and a helicopter.

Before play began on Saturday, the players gathered at center rink to honor Mr. Allen. Billy Barnwell, 59, of Woodside, recalled once how an all-white, all-star squad snubbed Mr. Allen by playing him third string. He scored seven goals in the first game and made first string immediately.

“He’d always hear racial stuff before the game, and I’d ask him, ‘How do you put up with that?’” Mr. Barnwell recalled. “Craig would say, ‘We’ll take care of it,’ and by the end of the game, he’d win guys over. They’d say, ‘This guy’s good.’”
