Question

Please draw a FBD as well!

The bearing consists of rollers, symmetrically confined within the housing. The bottom one is subjected to the force F at its contact A due to the load on the shaft. Suppose that F = 155 N. (Figure 1) Determine the magnitude of the normal reaction N_B on the bearing at its contact point B for equilibrium. Express your answer to three significant figures and include the appropriate units. Determine the magnitude of the normal reaction N_C on the bearing at its contact point C for equilibrium. Express your answer to three significant figures and include the appropriate units.

Explanation / Answer

Given,

F = 155 N

(B)forces along Y:

-Nc cos40 + 155 = 0

Nc = 155/cos40 = 202.34 lb

Hence, Nc = 202.34 lb

(B)Consider forces along X:

Nb - Nc sin40 = 0

Nb = Nc sin40 = 130.06 lb

Hence, Nb = 130.06 lb
