For personnel lifts, the total load must not exceed ...: 50% of the hoist's rated capacity. 39. To find the weight of a piece of aluminum plate, you would multiply ...: - square feet times material weight per square foot based on a specified thickness. 40. A triangular shaped 1 inch thick metal plate has a base of 10 feet and a height of 15 feet. What is the area of the plate?: 75 square feet 41. A circular shaped 1/2 inch thick aluminum plate has a diameter of 7 feet. What is the area of the plate rounded up?: 39 square feet 42. A complex shape of 1 inch thick aluminum plate has a rectangular area of 64 square feet and triangular area of 16 square feet. If aluminum weighs 14 pounds per square foot, how much does the plate weigh (rounded up to the nearest hundred pounds)?: 1,200 lbs 43. A complex shape of 1 inch aluminum plate measures 6 feet long on the top edge, 8 feet wide on the left edge, 12 feet long on the bottom edge, ending with a 10 foot long hypotenuse connecting back to the top edge. What is the correct equation to find the area of the triangular shape?: 8 x 6 / 2 6 / 8 44. The formula for determining the area of a triangular shaped object is:: - Base x Height divided by 2 45. A box has 27 cubic feet of sand in it. Sand weighs 105 lbs. per cubic foot. The box weighs 1,200 lbs. empty. The correct equation to find the total weight is:: 27 x 105 = 2,835 + 1,200 = 4,035 lbs 46. A cylinder has a diameter of 12 feet, and a height of 17 feet. What is the volume of the cylinder rounded up?: 1,922 cubic feet 47. A cylinder is made of solid aluminum which has a unit weight of 165 pounds per cubic foot.
