Question

For the situation shown in the figure, calculate F_R , the force exerted by the right hand. The pole is uniform and has a mass of 4.23 kg. The hands are 0.900 m apart, and the cg (center of gravity) of the pole is 0.62 m from the left hand.

For the situation shown in the figure, calculate F.R, the force exerted by the right hand. The pole is uniform and has a mass of 4.23 kg. The hands are 0.900 m apart, and the cg (center of gravity) of the pole is 0.62 m from the left hand F, I -ody diagram FR CGF

Explanation / Answer

Given,

m = 4.23 kg ;

Fr = 0.62/0.9 x mg

Fr = 0.62/0.9 x 4.23 x 9.81

Fr = 28.59

Hence, fr = 28.59 N

Fl + Fr = mg

Fl = mg - Fr

Fl = 4.23 x 9.81 - 28.59 = 12.91 N

Hence, fl = 12.91 N
