Calculate the moment about point A (center of post) when: W= 1000 lb & Q= 0 W = 1000 lb & Q = 400 lb Compute the moment of force F about point B using the following procedures: Determine the moment arm (d) and evaluate M=Fd Resolve force F into x and y components at point A and Calculate the moment Calculate the moment with F positioned at point C Calculate the moment with F positioned at D Use a vector approach (determinant) to find the moment Calculate the roller reaction at point B by taking a moment about point C Assume a weightless beam and a pin support at point C

Explanation / Answer

problem:-1

a-3000 lb-m

b-2200 lb-m

problem:-2

a-11.04 in and 276.15 lb-in

b-276.15

c-276.15

d-276.15

moment = rxf=12(length of lever arm*force component perpendicular to it)

so moment = 12*25cos(23)=276.15

prob:3-

a-9.6r+12-12+3.6=0

so r=-0.375
