Two forces p and q are applied as shown to an aircraft connection. knowing that the connection is in equilibrium and that p = 500 lb and q = 650 lb, determine the magnitudes of the forces exerted on the rods a and b.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
