42 A two-force member can be in static equilibrium only if the two forces are O (A) colinear O (B) equal O (C) equal, opposite, and colinear O (D) orthogonal

Solution

(42) ans is (c)

A two force member is a body that has forces ( only forces, no moments) acting on it in only two locations. In order to have a two force member in static equilibrium, the net force at each location must be equal, opposite, and collinear.

(43) ans is (c)

compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.
