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

A student wants to determine the coefficients of static friction and kinetic friction between a box and a plank by gradually raising one end of the plank. When the angle of inclination with the horizontal reaches 280 the box starts to slip and starts to slide 2.53 m down the plank in 3.92 s. Find the coefficients of friction.
A rigid rod resting on a fulcrum has the following 20-lbs forces acting on it. A is attached 2 feet from the left of the fulcrum acting vertical upward. B is 4 feet to the left of the fulcrum, acting downward at an angle of 30° with respect to the horizontal. C is 6 feet from the left of the fulcrum, acting upward with an angle of 45° with respect to the horizontal. D is attached 2 feet at the right of the fulcrum, acting downward at an angle of 60° respect to the horizontal. Where can a 20 lbs force be placed to put the system in equilibrium?
