Calculate the diameter of pin from shear consideration with maximum shear stress allowed is 40NN/mm² and an axial tensile force of 50kN is acting on the rod.

A)
39mm
B)
44mm
C)
49mm
D)
52mm

Correct Answer : Option (A) :   39mm

Explanation : As the pin is subjected to double shear diameter (D) = √(2P/π x τ) = 38.80mm.

Which type of rope drum is preferred?
A)
Drums with helical grooves
B)
Plain cylindrical drums
C)
Both are equally preferred
D)
None of the above

Correct Answer :   Drums with helical grooves

Explanation : They have more bearing surface of the drum and prevent friction between adjacent turns of the rope.

Small sheaves are preferred over large sheaves on what parameters?
A)
Higher cost of small sheaves
B)
Increasingly centrifugal force in large sheaves
C)
Preferring centrifugal force reduction even for more money
D)
None of the above

Correct Answer :   Increasingly centrifugal force in large sheaves

Explanation : Larger sheaves have higher centrifugal forces and higher cost because more material is used in their construction.

The wire rope is subjected to
A)
Tensile Stress
B)
Bending Stress
C)
Both bending and tensile stress
D)
None of the above

Correct Answer :   Both bending and tensile stress

Explanation : There is direct tensile stress due to load being raised as well as bending stress.
