find the reaction forces at point A and BSolutionHere for t

Solution

Here ,

for the raction force at the point A ,

balancing moment about B ,

FA * 20 - 20 * 10 - 30 * 10 * 10 = 0

FA= 160 lb

Now , at the point B

FA = FB

FB = 160 lbs

the reaction force at A is 160 Lb and reaction at B is 160 lbs
