Suppose you have a 100-kg box full of books resting on a wood floor, with coefficient of static friction 0.500 between these surfaces. A force is applied at an angle of 30° with respect to the horizontal, as shown. M (a) What is the minimum force would you need to exert on the box to get it to move? (b) If you continue to exert this force once the box starts to slip, what will be its acceleration? The coefficient of sliding friction is known to be 0.300 for this situation.
A helium balloon floats at the end of a string. The net force (the bouyancy force minus the weight) on the balloon is 33 N. If the tension in the string exceeds 54 N of force, the string will break. How great a force can a horizontal wind exert on the balloon before the string breaks?

A telephone cable is clamped at A to the pole AB. Knowing that the tension in the left-hand portion of the cable is T1 = 800 Ib, determine: a) the required tension T2 in the right-hand portion if the resultant R of the forces exerted by the cable at A is to be vertical. b) the corresponding magnitude of R. 25 T
