Q1
Easy
What is the formula for Young's modulus?
A.
Tensile stress / Tensile strain
B.
Tensile strain / Tensile stress
C.
Shear stress / Shear strain
D.
Bulk modulus / Volume strain
Show Answer & Explanation
Correct Answer: A
Young's modulus is defined as the ratio of tensile stress to tensile strain, indicating how much a material will stretch or compress under a given load.
Q2
Easy
Which property of a material is described by the term 'elastic limit'?
A.
The maximum stress before permanent deformation
B.
The ratio of stress to strain
C.
The change in length per unit length
D.
The resistance to tensile force
Show Answer & Explanation
Correct Answer: A
The elastic limit is the maximum stress that a material can withstand without undergoing permanent deformation, beyond which it will not return to its original shape.
Q3
Easy
If a rubber band is stretched, which of the following happens?
A.
It returns to its original length immediately after the force is removed
B.
It remains stretched permanently
C.
It loses its elasticity
D.
It can either return to original length or remain stretched depending on the extent of stretching
Show Answer & Explanation
Correct Answer: D
A rubber band can return to its original length if stretched within its elastic limit; if stretched beyond that, it may remain deformed.
Q4
Medium
A steel wire of length 2 m and cross-sectional area 1 mm^2 is stretched by a tensile force of 500 N. What is the strain in the wire?
A.
0.002
B.
0.001
C.
0.005
D.
0.0005
Show Answer & Explanation
Correct Answer: A
Strain is defined as the change in length divided by the original length. Here, we have the force, but we need Young's modulus to find change in length. However, if we use 500 N on a wire with area 1 mmยฒ, we can find stress, then relate it to strain through the formula. Assuming Young's modulus for steel is about 2 ร 10^11 N/mยฒ, strain would be stress/Young's modulus = (500 N / (1 ร 10^-6 mยฒ)) / (2 ร 10^11 N/mยฒ) = 0.002.
Q5
Medium
If the Young's modulus of a material is 200 GPa and the material is subjected to a tensile stress of 400 MPa, what is the resulting strain?
A.
0.002
B.
0.001
C.
0.005
D.
0.0005
Show Answer & Explanation
Correct Answer: A
Young's modulus (E) relates stress (ฯ) and strain (ฮต) as E = ฯ / ฮต. Rearranging gives ฮต = ฯ / E. Here, ฯ = 400 MPa = 400 ร 10^6 N/mยฒ and E = 200 GPa = 200 ร 10^9 N/mยฒ. Thus, strain ฮต = (400 ร 10^6) / (200 ร 10^9) = 0.002.
Q6
Medium
A rubber band is stretched to twice its original length under a certain load. What type of deformation does this represent?
A.
Elastic deformation
B.
Plastic deformation
C.
Viscous deformation
D.
Brittle deformation
Show Answer & Explanation
Correct Answer: A
Elastic deformation occurs when the material returns to its original shape once the force is removed. Stretching a rubber band to twice its original length is an example of elastic deformation since it can return to its original length after the load is removed.
Q7
Medium
A cylindrical rod of length L and radius r is subjected to a tensile force F. If the Young's modulus of the material is E, what is the extension ฮL of the rod?
A.
ฮL = (F * L) / (A * E)
B.
ฮL = (F * ฯ * rยฒ) / (E * L)
C.
ฮL = (E * F) / (A * L)
D.
ฮL = (A * E) / (F * L)
Show Answer & Explanation
Correct Answer: A
The extension ฮL of a rod under tensile stress is given by ฮL = (F * L) / (A * E) where A is the cross-sectional area (ฯrยฒ for a cylinder). Therefore, option A correctly represents the relationship.
Q8
Hard
A steel wire of length 2 m and cross-sectional area 1 mmยฒ is stretched by a load of 200 N. Calculate the elongation produced in the wire. (Young's modulus of steel = 2 ร 10ยนยน N/mยฒ)
A.
0.2 mm
B.
0.1 mm
C.
0.5 mm
D.
0.3 mm
Show Answer & Explanation
Correct Answer: A
Using the formula for elongation (ฮL = FL / (A * Y)), substituting values gives ฮL = (200 N * 2 m) / (1 ร 10โปโถ mยฒ * 2 ร 10ยนยน N/mยฒ) = 0.2 mm.
Q9
Hard
Which of the following materials exhibits the highest elasticity?
A.
Rubber
B.
Steel
C.
Glass
D.
Wood
Show Answer & Explanation
Correct Answer: B
Steel has a higher Young's modulus compared to rubber, glass, and wood, indicating it can withstand more stress before deforming permanently.
Q10
Hard
A cylindrical rod of length 1 m and radius 5 mm is subjected to a tensile stress of 400 MPa. If the Young's modulus of the material is 200 GPa, what is the strain produced in the rod?
A.
0.002
B.
0.004
C.
0.006
D.
0.008
Show Answer & Explanation
Correct Answer: A
Strain is calculated using the relation stress = Young's modulus ร strain. Rearranging gives strain = stress / Young's modulus, which equals 0.002.
