Test: Cotter Joint - Question 3
Save

Can the cotter joint be used to connect slide spindle and fork of valve mechanism?

Detailed Solution for Test: Cotter Joint - Question 3

Explanation: As long as axial forces act, cotter joint can be employed.

Test: Cotter Joint - Question 4
Save

Which of the following is not a part of cotter joint?
Detailed Solution for Test: Cotter Joint - Question 4

Explanation: There is no point of mentioning collar alone in a cotter joint. It has to be a spigot collar or socket collar.

Test: Cotter Joint - Question 5
Save

Cold riveting holds the connected parts better than hot riveting.
Detailed Solution for Test: Cotter Joint - Question 5

Explanation: The compression of connected parts in hot riveting causes friction, which resist sliding of one part with respect to other. This force is greater in hot riveting.

Test: Cotter Joint - Question 6
Save

In cold riveting like hot riveting shank is subjected to majorly tensile stress.
Detailed Solution for Test: Cotter Joint - Question 6

Explanation: In cold riveting there is no reduction in length and hence no tensile stress. Shear stress dominates.

Test: Cotter Joint - Question 7
Save

Determine the width of the cotter used in cotter joint connecting two rods subjected to axial load of 50kN and permissible shear stress in cotter is 50N/(mm² ). Given thickness of cotter=10mm
Detailed Solution for Test: Cotter Joint - Question 7

Explanation: Cotter is subjected to double shear hence width=P/(2*τ*t).

Test: Cotter Joint - Question 8
Save

If the joint is to fail by crushing of the socket collar, determine the required diameter of the socket collar so that the compressive stress does not exceed 126.67 N/mm². Given: Permissible compressive stress = 126.67 N/mm²; Spigot diameter = 65 mm; Collar thickness = 15 mm; and Applied force P. Note: Without the value of P, it is impossible to compute a unique numerical answer for the socket collar diameter.
Detailed Solution for Test: Cotter Joint - Question 8

a) Cannot be determined (insufficient data)

The compressive stress is defined as the applied force P divided by the net area [(socket diameter – spigot diameter) × collar thickness]. However, since the applied force P is not provided, it is impossible to determine a numerical value for the socket collar diameter. To solve this problem, the value of P must be specified or assumed.

Test: Cotter Joint - Question 9
Save

 Cotter joint can be used to connect two rods for torque transmission purpose.
Detailed Solution for Test: Cotter Joint - Question 9

Explanation: Cotter Joint is never used to connect two rods for torque transmission purpose.

Test: Cotter Joint - Question 10
Save

Thickness of plate is required more in welding than in riveting.
Detailed Solution for Test: Cotter Joint - Question 10

Explanation: In riveting, cross section is weakened due to the holes and to compensate this, thicker plates are required in riveting.
