Question

Derive an expression for angle of repase
​

Answer 1

Answer:

The angle of repose:- it is the minimum angle that an inclined plane makes with the horizontal when a body placed on it just begins to slide down.

let any inclined plane inclined with θ angle with horizontal and a body which mass is m just begins to slide down.

then,

mg.sinθ = μN

where μ is the coefficient of friction and N is the normal reaction.

N = mg.cosθ

now,

mg.sinθ = μmg.cosθ

tanθ=μ

θ=tan − 1(μ)

here θ is known as angle of repose
