In the figure, a lead brick rests horizontally on cylinders A and B. The areas of the top faces of the cylinders are related by AA= 1.7 AB; the Young's moduli of the cylinders are related by EA= 1.9 EB. The cylinders had identical lengths before the brick was placed on them. What fraction of the brick's mass is supported (a) by cylinder A and (b) by cylinder B? The horizontal distances between the center of mass of the brick and the centerlines of the cylinders are dAfor cylinder A and dB for cylinder B. (c) What is the ratio dA/dB?
A father and his daughter are playing a see-saw made of a plank of length 5.1 m and of weight 118 N in a park. If the daughter weights 274 N and sits at one edge of the plank, where the father with a weight of 523 N should sits from the pivot point to balance the see-saw in m, assuming that the plank has uniform density? Keep three significant figures.
A three-legged wooden bar stool made out of solid Douglas fir has legs that are 2.0 cm in diameter. When a 75 kg man sits on the stool, by what percent does the length of the legs decrease? Assume, for simplicity, that the stool’s legs are vertical and that each bears the same load.

From slow-motion video, the speed of his 1.50-kg hand descending on a block was estimated to be 15.0 m/s, which decreased to a speed of 0.500 m/s in the 2.50 103 s during which his hand made contact with and broke through the block. The maximum shear stress a concrete block can be subjected to before breaking is 9.50 105 N/m2. a. What was the force exerted by Lees hand on the block? b.

- To get up on the roof, a person with a mass m = 71 kg leans an aluminum ladder (mass 10.5 kg and length 6.0 m) against the house on a concrete pad with the base of the ladder 2.00 m from the house. The ladder just overhangs a plastic rain gutter, which we can assume to be frictionless, so the force from the gutter on the ladder acts perpendicularly to the ladder. As a result, the top of the ladder experiences a normal force at an angle, while the bottom of the ladder experiences both a vertical normal force and a horizontal friction force. The center of mass of the ladder is 2 m from the bottom. The person is standing 3 m from the bottom. a.) What is the magnitude of the net force on the ladder at the top?
