The 52lb mulching machine has a center of gravity at G Deter

The 52-lb mulching machine has a center of gravity at G.

Determine the vertical reactions at the wheels C and B and the smooth contact point A.

Find NB,NC,NA

Solution

Here NB and NC will be same as it is symmetric about x-axis.

So taking moment about A, 1.5*52 = 2 * (1.5+2)*NB, so NB=NC =11.14 lb.

From Force balance in z-direction, NA = 52-2*11.14 = 29.72 lb
