An engineer conducts a tensile test for ductile material, britte material, and malleable material. based on the experimental data, the stress-strain curve for the three materials is developed for which of the following materials is the stress-strain curve steeper (has higher slope)? a)-ductile material b)-brittle material c)-malleable material d)-none of the other answers

Suppose that a cylindrical tank 6 meters high with a radius of 2 meters is filled to the rim with water. the tank is buried so that the top of the tank is 1 meter below ground level. the space above the tank is not filled with water. calculate how much work needs to be done by a pump to pump the water out of the tank up to ground level. (the water weighs 9,800 newtons per cubic meter.)
