A massless bar of length L : 1.63m is held in equilibrium as shown in the diagram below. The bar makes an angle of 6 with the horizontal. The upper end of the bar is attached to a rope which exerts a force of magnitude T > ON in the negative x-direction. g A ball of mass m : 6.34kg is suspended from the bar a distance 3 along the bar. The bottom of the bar is held in place on a rough horizontal surface by friction. The coefficient of static friction between the bar and the surface is p = 0.31. (The input below will accept answers with no more than 1% variation from the correct value.) For what angles can the bar be in equilibrium? degrees g 9 g degrees A massless bar of length L 2 1.54m is held horizontally in equilibrium as shown in the diagram. The left end ofthe bar is held in place by a hinge. On the right end of the bar there is a box of mass M = 32.6kg. At a distance 3 2 0.91m from the left end of the bar there is a rope under tension T which makes an angle 6 2 508 with the vertical as shown. (The input below will accept answers with no more than 1% variation from the correct value.) What is the x-component of the force on the bar by the hinge? N What is the z-component of the force on the bar by the hinge? N A uniform bar of mass M = 18.3kg has a mass m = 16.5kg attached three quatters of the way from its left end. The bar is supported in equilibrium by two vertical ropes at the left and right ends under tension T1 and T2 respectively. The bar has a length L = 3.23111. This is shown in the diagram. (The input below will accept answers with no more than 1% variation from the correct value.) What is T1? N What is T2
