Question

A force T having a magnitude of T=2500N acts at a point B of the bracket as shown in the figure.

(Please show your work)

a. Replece the force T acting at B by an equavalent resultant force and couple moment at point A.Express your resuts in vector form.

b.Find the moment of the force T about the axis AC.

A force T having a magnitude of T=2500N acts at a point B of the bracket as shown in the figure. Replace the force T acting at B by an equavalent resultant force and couple moment at point Express your results in vector form. Find the moment of the force T about the axis AC.

Explanation / Answer

1)force at A will be in same dierection and magnitude Ta=2400 N

now moment at A = - 2500 (200/250) 200 j - 2500 (150/250) 320 i = - 40*10^4 j -48 *10^4 i

2) T = 2500 ( -200 i + 150 k)   

AC= ( 240,-320,0)

Moment = T x AC
