Neglecting friction and the weight of the member determine t

Neglecting friction and the weight of the member, determine the reactions exerted on the bar at the three contact points.

Solution

Sol. The reaction on point A,B and C are calculated as Follows:

Ra= Fsin30*.15

Rb=Fcos30*0.2

Rc=Ftan20*.4

Here F=200N

so Ra=200sin30*.15=15N

Rb=200cos30*.2=34.64N

Rc=200tan20*0.4=200*0.36397023*.4= 29.04N
