To help workers in your project site move dozens of equipment weighing 70 kgs to a height of 2.2m, you decided to apply the concept of simple machine. You want an inclined plane to be built. Given the angle between the incline and the ground, what would be the most efficient incline to be built to raise the equipments? Why? Here are the angles you can choose from for your incline: a. 15°; b. 30°; c. 60°

A tank, shaped like a cone has height 8 meters and base radius 3 meters long. It is placed so that the circular part is upward. It is full of water, and we have to pump it all out by a pipe that is always leveled at the surface of the water. Assume that a cubic meter of water weighs 10000 N, i.e. the density of water is 10000 N/m3. How much work does it require to pump all water out of the tank? Enter the exact value of your answer.
