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
