Consider the following figure with load W 105 lb 10 in 10 in

Consider the following figure with load W= 105 lb. 10 in.- 10 in. 12 in References eBook & Resources Difficulty: Easy Section Break value 10.00 points Determine the reactions at A and B when 0° (Round the final answer to one decimal place) When = 0 Magnitude of reaction forces at A is lb and B is lb

Solution

reaction at A is W/2 = 105/2 = 52.5 lb vertical

reaction at B is W/2 cos 30 = 52.5 cos 30 = 45.4663 lb vertical to surface
