This makes a ramp 10 ft long from one end to the other. We then place the 5 kg cube at the top of the ramp and let it go. How long will it take for the cube to reach the end of the 10 ft ramp?arrow_forwardTension and compression occur in a partially supported horizontal beam when it sags due to gravity or when it supports a load. Make a simple sketch to show a means of supporting the beam so that tension occurs at the top part and compression at the bottom.

- A gas station stores its gasoline in a tank under the ground. The tank is a cylinder lying horizontally on its side. (In other words, the tank is not standing vertically on one of its flat ends.) If the radius of the cylinder is 2 meters, its length is 3 meters, and its top is 5 meters under the ground, find the total amount of work needed to pump the gasoline out of the tank. (The density of gasoline is 673 kilograms per cubic meter; use g=9.8 m/s^2')arrow_forwardWhy is a water tower generally placed on top of a hill?
