Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle? FIGURE P5.76

If the coefficient of static friction is 0.800 between each pair of surfaces in contact, what force must be applied horizontally to the 4.00-kg block to make it move?
A box weighing 50 N rests on a horizontal surface. A person pulls with a force of 10N to the right and it does not move. In order for you to move, you need another person who pulls vertically. What is the minimum force that the other person needs to exert in order for it to move? Coefficient of static friction = 0.4
