Didn't get any of the explanation. Can anyone explain it in a simpler way?

Please state the condition regarding friction.

@Sourav Kundu.

You can be right but in this question angle is made b/w horizontal and inclination.

So cos(90°-x) = sin x.

So right answer is (A).

I think it should cosθ because weight is acting is down.

Opposite side= sinθ.
Base= cosθ.

Because opp.side/hypo=sinθ(hypo=1).
sin2θ+cos2θ=1.

What is the difference between effort and load?

Hemendra said:   1 decade ago
Can anyone explain briefly?

Weight acts in vertical direction. So, sin 0.

Please answer me this question with the help of diagram.

How you considered that the base as Cos theta?
