A cantilever of span 4 m carries a point load at the free end. If the slope is 2°(0.035 radian), the deflection at the free end would be nearest to

A beam 3 meters in length is simply supported at its ends and carries a point load W at its center. If the slope at the ends is not to exceed 1 °(0.01745 radian), the limiting deflection at the center of beam would be

Consider the following theorem related to strain energy: “For a linear elastic structure subjected to two sets of forces, the work done by the first set through the displacement produced by the second set is equal to the work done by the second set through the displacements produced by the first set’’ The theorem is

The internal strain energy stored within an elastic bar subjected to a torque T is
