A weightless cantilever beam of span L is loaded as shown in the figure. For the entire span of the beam, the material properties are identical and the cross-section is rectangular with constant width. 3. From the flexure-critical perspective, the most economical longitudinal profile of the beam to carry the given loads amongst the options given below, is

A rigid, uniform, weightless, horizontal bar is connected to three vertical members P, Q and R as shown in the figure (not drawn to the scale). All three members have identical axial stiffness of 10 kN/mm. The lower ends of bars P and R rest on a rigid horizontal surface. When NO load is applied, a gap of 2 mm exists between the lower end of the bar Q and the rigid horizontal surface. When a vertical load W is placed on the horizontal bar in the downward direction, the bar still remains horizontal and gets displaced by 5 mm in the vertically downward direction. 2. The magnitude of the load W (in kN, round off to the nearest integer), is 2. 2. [GATE 2020: 2 Marks, Set-1]

A prismatic linearly elastic bar of length, L, cross sectional area A, and made up of a material with Young's modulus E, is subjected to axial tensile force as shown in the figures. When the bar is subjected to axial tensile force P1 and P2 the strain energies stored in the bar are U1 and U2 respectively. 1. 1. P_{1} 1. 1. P_{2} 1. 1. (P_{1} + P_{2}) 1. 1. If U is the strain energy stored in the same bar when subjected to an axial tensile force (P1 + P2) . the correct relationship is 1. 1. (a) U = U1 - U2 (c) U < U1 + U2 1. 1. (b) U = U1 + U2 1. 1. (d) U > U1 + U2 1. 1. [GATE 2020: 2 Marks, Set-II]
