17-85. The bar has a weight per length of w. If it is rotating in the vertical plane at a constant rate w about point 0, determine the internal normal force, shear force, and moment as a function of x and 0.

11-17. Draw the sheur and moment diagrams for the rod. It is supported by a pin at A and a smooth plate at B. The plate slides within the groove and so it cannot support a vertical force, although it can support a moment. 15 KN -2 m-

*7-36. Determine the normal force, shear force, and moment acting at points B and C on the curved member. Problem 7-36 B 2 ft 45° 30° 3 500 lb

Show FBD and complete solution.    The pin spanner is used to turn shafts and collars. If a moment of is required to turn the 200-mmdiameter collar about its center O under the action of the applied force P, determine the contact force R on the smooth surface at A. Engagement of the pin at B may be considered to occur at the periphery of the collar.

P7-4. Determine the internal normal force at section A if the rod is subjected to the external uniformally distributed loading along its length of 8 kN/m. 8 kN/m 3m

21-50. The bent uniform rod ACD has a weight of 5 lb/ft and is supported at A by a pin and at B by a cord. If the vertical shaft rotates with a constant angular velocity w = 20 rad/s, determine the x, y, z components of force and moment developed at A and the tension in the cord. -1 t- -0.5 ft- |B 1 ft
