Q.6] The inclined members carrying compressive loads are
Strut
Post
Winch
Pedestal
Explanation : The inclined member carries compressive loads in case of frames and trusses are known as Struts. The Pedestal is a vertical compression member whose effective length is less than 3 times its least lateral dimension.
