Question

Determine the minimum amount of the force P required to remove the wedge shown. Take the value of the coefficient of friction to be 0.3. Assume that the block doesn’t slip at C.

(a) 1.15 KN

(b) 2.15 KN

(c) 3.15 KN

(d) 4.15 KN

I have been asked this question in homework.

Query is from Wedges topic in division Friction of Engineering Mechanics

Answer 1

Correct choice is (a) 1.15 KN

Easiest explanation: The normal force at A is 2381 N. The normal force at B is 2452.5 N. The angle of the wedge over which the block is being slided is generally taken out by the help of the tangent inverse trigonometric function. Thus the answer.
