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 lumbar portion of the human spine supports the entire weight of the upper torso and the force load imposed on it. We consider here the disk (shaded red) between the lowest vertebra of the lumbar region (L5) and the uppermost vertebra of the sacrum re- gion. (a) For the case L 0, determine the com- pressive force C and the shear force S supported by this disk in terms of the body weight W. The weight W, of the upper torso (above the disk in question) is 68% of the total body weight W and acts at G,. The vertical force F which the rectus muscles of the back 25 mm G1 W L3 L4 L5 G2 4r exert on the upper torso acts as shown in the figure.

If the co-efficient of friction between the nut and screw is 0,095 and outer diameter of screw s 6 cm, find the force required atthe end of the handle of length 50 cm to ift the load. (20 M)
The figure shows a mechanism that raises packages in a transfer mechanism. A 500-N package sits on the horizontal output link O4BD while the crank O2A is rotating at constant speed of 400 rpm CW. At the position shown the crank OA is vertical and the output link O4B is horizontal. we need to determine the torque required from the motor at the crank 02A and the force in member AB The weights of the links are negligible. 30mm 450mm 500N 220 mm B 374 mm 374 mm The angular velocity of the link O,BD in rad/s is = The magnitude of the velocity of point D in m/s is =
