i. Reduce the system to an equivalent resultant force F R and moment couple M R

Question

i. Reduce the system to an equivalent resultant force FR and moment couple MR at A.
ii. Relative to point A, further reduce the applied loading system (moment couple and forces) to
a single force placed at a proper position on the beam; determine this position.
iii. Determine the reactions that the wall exerts on the beam to preserve static equilibrium.

Reduce the system to an equivalent resultant force FR and moment couple MR at A. Relative to point A, further reduce the applied loading system (moment couple and forces) to a single force placed at a proper position on the beam; determine this position. Determine the reactions that the wall exerts on the beam to preserve static equilibrium.

Explanation / Answer

solving using equilibrium of equations
sum of x- axis= Rx+40cos45 =0
sum of y axis = Ry+30+40sin45=0
moment about point a Ma=03x30 + 6x40sin45 +150 =0
solving these 3 you wil get answer..
