Question 2

Find the reaction on the roller support in kN of the beam shown in figure. It is subjected to uniformly varying load with maximum of 10kN/m at fixed end and zero at free end as shown in figure below. ( consider Beam is propped at free end )

Question 3

The flexural rigidity (EI) of a cantilever beam is assumed to be constant over the length of the beam shown in figure. If a load P and bending moment PL/2 are applied at the free end of the beam then value of the slope at the free end is

Question 4

Autofrettage is a method of

Question 5

The normal stresses on two perpendicular planes through a point in a stressed material are 80 MPa (tensile) and 20 MPa (tensile) respectively. A shear stress of 40 MPa is also acting on these planes. What is the value of maximum shear stress at the point?

Question 6

The diameter of a solid shaft is D. the inside and outside diameters of a hollow shaft of same material and length are $Description: F:\GradeStack Courses\GATE Tests (Sent by Ravi)\GATE-22-April\GATE-IES-ME-Strength-of-Materials_files\image373.png$ and $Description: F:\GradeStack Courses\GATE Tests (Sent by Ravi)\GATE-22-April\GATE-IES-ME-Strength-of-Materials_files\image374.png$ respectively. What is the ration of the weight of the hollow shaft to the solid shaft?

Question 7

U₁ and U₂ are the strain energies stored in a prismatic bar due to axial tensile force P₁ and P₂ respectively. The strain energy U stored in the same bar due to combined action of P₁ and P₂ will be ________.
