Which one of the following statements is true regarding the normal force? At any instance there can only be one normal force acting on an object. At static equilibrium, the normal force on the object is equal to zero. ONormal force always points perpendicular to the surface the object is in contact with. The normal force is equal to the weight of the object.

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 painter with 80 weight is on a 4 meters long platform. Platform has negligible weight. The painter is balanced by two cables. One is at the left end and the other one is 3.2 meters away from the first cable. a)What is the tension on the left cable and the right cable when the painter is in the middle of the platform b)Would the painter be able to move the right end of the platform without loosing balance. Calculate the tensions on the cables for that case and show that it leads to a negative tension.
