In the figure, a thin horizontal bar AB of negligible weight and length L = 3.2 m is hinged to a vertical wall at A and supported at B by a thin wire BC that makes an angle 0 = 44° with the horizontal. A block of weight W = 170 N can be moved anywhere along the bar; its position is defined by the distance x = 0.887 m from the wall to its center of mass. Find (a)...
A m = 2.45 kg object hangs in equilibrium at the end of a rope (taken as massless) while a wind pushes the object with a F W = 15.7 N horizontal force. Find the magnitude of the tension in the rope and the rope's angle from the vertical. The acceleration due to gravity is g = 9.81 m/s2. A ball attached to the end of a rope hangs from an overhead support. The rope is straight, and hangs at...
