_______ is the capacity of material to absorb energy when it is elastically deformed and then upon unloading, to have this energy recovered.

Detailed Solution for Test: Solid Mechanics- 1 - Question 3

Resilience: It is energy absorbed by a member in elastic region. It denotes the capacity of material to absorb energy when it is elastically deformed and then upon unloading, to release this energy.

Toughness: It is energy absorbed by member just before its fracture.

A steel plate of side ‘a’ (2d) is enclosed in a closely fitting rigid support as shown. Assume friction between plate and support is zero. Determine the free expansion in x - direction of the plate due to heating by ΔT – (Poison ratio is μ & thermal co - eff. α)
Detailed Solution for Test: Solid Mechanics- 1 - Question 8

σx = 0
σy = −αTE
εy = −αT
εx = −μεy = μαT = δa/a
ϵx = Free expansion due to temperature change + Expansion due to lateral strain

= a α Δ T + μ a α Δ T (due to y direction)

= a α Δ T (1 + μ)

For a cylindrical bar of 30 mm dia& 900 mm length, during a tension test, it is found that longitudinal strain is 4 times of lateral strain. The bulk modulus for the bar is (X) × 105 N/mm2  (if E = 3 × 105 N/mm2) The value if X is ___________

Detailed Solution for Test: Solid Mechanics- 1 - Question 9

E = 3 × 105 N/mm2 & E = 3k (1 – 2μ).....(1)
From (1) we get K = E/3(1−2μ) [∴μ=0.25 given]
put μ=0.25 in equation 1,we get
k=2*105N/mm2.
