Question 1

Lead as a material used in construction has E= 15 GPa and K= 50 GPa. What its Poisson’s Ratio?

Question 2

If p₁ and p₂ are the principal stress at a point in a strained material with Young’s modulus E and Poisson’s ratio

, then what is the principal strain?

Question 3

What is the reaction on the pin C for a beam as shown in the figure below ?

Question 4

A cantilever AB is loaded as shown in the figure given below. What is the shape of the bending moment diagram for portion AC?

Question 5

Statement (I) : In simple bending, strain in the bent beam varies linearly across the beam depth.
Statement (II): As per Hooke’s law, within elastic limit, the stress is proportional to the strain.

Question 6

The bending moment diagram of beam is shown in the figure.

The shear force diagram of the beam is represented by

Question 7

For the simply supported beam, shown in the figure given below, at what distance from the support A, is the shear force zero?

Question 8

Group I gives the shear force diagrams and Group II gives the diagrams of beams with supports and loading. Match the Group I with Group II.
Group – I Group – II

Question 9

Assertion (A) : The failure occurs of an axially loaded mild steel tension specimen of circular cross-section is along a plane at 45⁰ to the axis of the specimen.
Reason (R) : The failure occurs an a plane of the specimen subjected to maximum shear stress and mild steel is relatively weak in shear.

Question 10

The bending moment at C for the beam shown in the figure is
