A group of 10 steel plates are to be hoisted. The plates measure 28.44 feet long and 140 feet wide. Each plate is 0.71 inches thick. Calculate the total load weight if all plates were to be lifted at once (use the field rule of thumb) show answer to 2 decimal places) Answer: A large copper disc is to be lifted. Before hoisting a load weight is required. Calculate the weight of the solid copper disc ( Copper weighs 560 pounds per cubic foot. Assume pi=3.14) Answer to the nearest whole pound Outer diameter 83.4 inches Thickness 1.2 inches Answer: You are required to lift 11 pieces of steel pipe. The pipe has a diameter of 1.3 inches and a thickness of 0.9 inches All pipes are 21 feet long.The pipes will all be lifted as one bundle. ( use the field rule of thumb for calculations, assume pi=3.14) Answer to the nearest whole pound. Answer: Use the field rule of thumb to calculate the following load weight. A rectangular tank with these dimensions. The tank is sealed (top and bottom) and made of steel plate (assume pi=3.14) Height 16.5 feet Length 29.6 feet Width 8.8 feet Steel thickness .38 inches Answer: You are required to lift an open top steel tank. The tank has the following dimensions Height 20.8 feet Length 22 5 feet Width 9.1 feet Steel thickness 0.9 inches Use the field rule of thumb for calculations. Answer to the nearest whole pound
