spring-loaded spray

A spray nozzle for a garden hose requires a force F= 5 lb. to open the spring-loaded spray chamber AB. The nozzle hand grip pivots about a pin through a flange at O. Each of the two flanges has thickness t = 1/16 in., and the pin has diameter dp = 1/8 in. [see figure part (a)]. The spray nozzle is attached to the garden hose with a quick release fitting at B [see figure part (b)]. Three brass balls (diameter db = 3/16 in.) hold the spray head in place under water pressure force fp = 30 lb. at C [see figure part (c)]. Use dimensions given in figure part (a).

(a) Find the force in the pin at O due to applied force F

(b) Find average shear stress τaver and bearing stress σb in the pin at O.

(c) Find the average shear stress Ï„aver in the brass retaining balls at C due to water pressure force fp.
