A punch of 20 mm diameter is used to punch a hole in an 8 mm thick plate. If the force required to create a hole is 110 kN, the average shear stress in the plate will be near.
ANSWER= [C] 220mpa
A punch of 20 mm diameter is used to punch a hole in 8 mm thick plate. If the force required to create a hole is 110 kN, the average shear stress in the plate will be nearly 220mpa.
Detailed Explanation
Diameter of punch (d) = 20 mm
Thickness of plate (f) = 8 mm
Panching force = Shear regijin force
110 × 10^3 = ? (π × d × t)
(110 × 10^3)/(π × d × t) = ?
? = (110 × 10^3)/(π × 20 × 8)
? = 220 mpa
Maximum carbon content in high strength deform bars should not be more than
ANSWER= [C] 0.30%
Maximum carbon content in high strength deform bars should not be more than 0.30%.
Effective thickness of a fillet weld is _____
ANSWER= [A] A function of the angle between fusion faces
Effective thickness of a fillet weld is a function of the angle between fusion faces.

ANSWER= [D] Shear force changes sign
Maximum bending moment in a beam occurs at Shear force changes sign
The stiffness of a helical spring is expressed as _____
ANSWER = [B] Load per unit deflection
The stiffness of a helical spring is expressed as Load per unit deflection
