Sin (theta) is correct.

When the angle is given with respect to horizontal, then in Y axis sin theta is taken.

Which one is correct? Please explain the correct answer.

It is simply inclination with respect to X & Y axis. So angle made with Y axis is Sin θ.

Since, v = u+at,

v1= gsin (theta)t, u = 0, a = g cos(90-theta) = g sin(theta).

v2 = gt.

So, v2/v1 = sin(theta).

V.R = (Distance moved by effort)/(Distance moved by lode).

Since effort is vertical so it will be P sinθ and load will be:

I = (p sinθ)^2+(p cos θ)^2

@Manoj.

Angle touch to horizontal axis i.e. base hence it is cos.

Manoj said:   10 years ago
How you considered that the base as Cos theta?

Please answer me this question with the help of diagram.

Weight acts in vertical direction. So, sin 0.
