Test: Knuckle Joint - Question 3

A maximum of how many roads may be connected using a knuckle joint?

Detailed Solution for Test: Knuckle Joint - Question 3

Explanation: In rare explanation, two rods with forks and one rod with eye is connected.

Test: Knuckle Joint - Question 4

A knuckle joint is also called socket pin joint.

Detailed Solution for Test: Knuckle Joint - Question 4

Explanation: A knuckle joint is also called a Forked Pin Joint.

Test: Knuckle Joint - Question 5

Which of the following are important parts of knuckle joint?

Detailed Solution for Test: Knuckle Joint - Question 5

Explanation: All the mentioned parts are important components of knuckle joint.

Test: Knuckle Joint - Question 6

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.

Detailed Solution for Test: Knuckle Joint - Question 6

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

Test: Knuckle Joint - Question 7

 If knuckle joint is to fail by crushing failure of pin in fork, then determine the diameter of knuckle pin when 50kN axial tensile force act on rods. Given: Max allowable compressive stress=25N/mm², thickness of each eye of fork=25mm.

Detailed Solution for Test: Knuckle Joint - Question 7

Explanation: d=P/2aσ = 40mm.

Test: Knuckle Joint - Question 8

If any cross section is subjected to direct tensile stress and bending stress, then find the dimension of cross section. Given length & breadth are t and 2t respectively. F=25kN acts on the top fibre of the cross section, M=F x t . Also maximum allowable tensile stress =100N/mm².

Detailed Solution for Test: Knuckle Joint - Question 8

Explanation: σ= [P/A] + [My/I], where y=t & I=t(2t)ᴲ/12.

Test: Knuckle Joint - Question 9

A knuckle joint can be used in valve mechanism of a reciprocating engine.

Detailed Solution for Test: Knuckle Joint - Question 9

Explanation: Knuckle joint can be used till the rods coincide or intersect in a plane.
