Example 3. A spring has a natural length of 20 cm. A force of 20 N is required to hold this spring at length of 30 cm. (a) Compute the work done to stretch the spring from 20 cm to 30 cm. (b) Compute the work done to stretch the spring from 30 cm to 40 cm. Example 4. A cable that weights 21b/ft is used to lift 800lb of coal up a mine shaft 500ft deep. Find the work done in lifting the coal from the bottom of the mine shaft to the top.

Brake pedals in cars 1 When you step on the brakes, you are compressing a narrow piston (radius 2 cm), creating pressure in a closed system. Mechanical advantage is gained by having the fluid in-turn compress a larger piston (radius 10 cm). If you apply a force of 20 N to the small piston, what is the force delivered to the large piston? If the small piston compresses by a distance of 5 cm, how much does the large cylinder move by? www.explainthatstuff.com 2 3 67 40₁0 8
Trina is a gym goer with a leg length of 84 cm. Suppose that she is in the gym doing straight legraising with 10 lb weights. Compute for the force that the muscle should exert in order to (1) maintain it in the position and(2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm,distance of the weight is 80 cm, and the COM is 45 cm from the joint. ANSWER THE QUESTION: 1.) Assuming that the leg moves at 0. 9 seconds, compute for the angular velocity. GIVEN: Leg length = 84 cm = 0.84 m Distance of the muscle from the joint = 54 cm = 0.54 m Distance of the weight = 80 cm = 0.80 m Distance of the COM from the joint = 45 cm = 0.45 m Mass = 10 lb = 4.535 kg Linear displacement x = 38.971 cm Or x = 0.389 m
