Test: Levers - Question 3

 The distance between fulcrum and dead weights is 100mm. Dead weights are of 2945.2N. An effort of 294.52N acts on the other hand. Find the distance between the fulcrum and other end of the lever.

Detailed Solution for Test: Levers - Question 3

Correct Answer :- B

Explanation : F₂ x l₂ = F₁ x l₁

2945.2 * 100 = 294.52 * l₁

l₁ = 1000mm

Test: Levers - Question 4

A right angled bell-crank is designed to raise a load of 5kN at short arm whose length is 100mm. Longer arm is of length 500mm. Calculate the reaction or force acting on the fulcrum.

Detailed Solution for Test: Levers - Question 4

Explanation: Force required for raising at longer end is found by F ₂xl₂ =F₁ xl₁. Reaction at fulcrum is
√ (F₁²+F₂²) as the two forces are perpendicular.

Test: Levers - Question 5

A right angled bell-crank is designed to raise a load of 5kN at short arm whose length is 100mm. Also longer arm is of length 500mm. If permissible bearing pressure on pin is 10N/mm² and diameter of the 20mm, find the length of the pin.

Detailed Solution for Test: Levers - Question 5

Explanation: R=p x d x L. Here R=√ (F₁²+F₂²).

Test: Levers - Question 6

A right angled bell-crank is designed to raise a load of 5kN at short arm whose length is 100mm. Also longer arm is of length 500mm. If permissible bearing pressure on pin is 10N/mm² and diameter of the 20mm, find the shear stress in the pin.

Detailed Solution for Test: Levers - Question 6

Explanation: τ=R/(2 x π x d²/4) as the pin is subjected to double shear. Also R=√ (F₁²+F₂²) and F ₂xl₂ =F₁ xl₁.

Test: Levers - Question 7

 How many classes of levers are there?

Detailed Solution for Test: Levers - Question 7

Explanation: The three classes are Fulcrum in the middle, Resistance in the middle and Effort in the middle.

Test: Levers - Question 8

 A bottle opener belongs to which class of the levers.

Detailed Solution for Test: Levers - Question 8

Explanation: In a bottle opener fulcrum can be considered at the end and resistance in middle as the actual work is done on the bottle cap which lies in middle of opener.

Test: Levers - Question 9

Fulcrum can be located at one end of the lever.

Detailed Solution for Test: Levers - Question 9

Explanation: Fulcrum can be located in middle or at one end of the lever.
