As a torque activity, your Physics TA sets up the arrangement shown below.m1m2A uniform rod of mass m,251 g and m2163 g and length L100.0 cm is attached to the wall with a pin as shown. Cords are attached to the rod at the r,10.0 cm and r,90.0 cm mark, passed over pulleys, and masses of187 g are attached. Your TA asks you to determine the following.(a) The position r, on the rod where you would suspend a mass m, = 200 g in order to balance the rod and keep it horizontal if released from a horizontal position. In addition, for this case, what force (magnitude and direction)does the pin exert on the rod? Use standard angle notation to determine the direction of the force the pin exerts on the rod. Express the direction of the force the pin exerts on the rod as the angle 0-, measured with respect tothe positive x-axis (counterclockwise is positive and clockwise is negative).r3m%|F.N(b) Let's now remove the mass m, and determine the new mass m, you would need to suspend from the rod at the positionra= 20.0 cm in order to balance the rod and keep it horizontal if released from a horizontal position.

The light boom AB is attached to a vertical wall by a ball and socket joint at A and supported by two cables at B. A force P is applied at B where P = 18i - 15j kN.Note that the reaction force at A acts along the boom because it is a two-force member. Calculate the magnitude of the reaction force at A in kN.

The bent rod in Fig. a is supported at A by a journal bearing, at D by a ball-and-socket joint, and at B by means of cable BC. Using only one equilibrium equation, obtain a direct solution for the tension in cable BC. The bearing at A is capable of exerting force components only in the z and y directions since it is properly aligned on the shaft. In other words, no couple moments are required at this support. 1m B. 0.5 m Free-Body Diagram. As shown in Fig. b, there are six unknowns 05 m Equations of Equilibrium. The cable tension Tg may be obtained directly by summing moments about an axis that passes through points D and A. Why? 00 kg (a) Since the moment arms from the axis to T, and W are easy to obtain, we can determine this result using a scalar analysis.
