an object is at rest on a frictionless incline supported by a string parell to the incline. What is the magnitude of the tension in that string in terms of mass of the object and the incline angle theta. What forces would be found on the mass. I know that there are no numbers. Problem is supposed to make you think
No numbers

Let (theta) the angle of the elevation.
The forces acting on the mass are:
a) Gravity, g*sin(theta)
b) Normal, perpendicular to the plane. N=g(theta+1/2pi)
So the sum of the forces is a) + b).
Tension in the wire is equal to the sum.

Yup, no numbers, only mass, angle time and length
m, t, l and alpha.
Know the answer? It's easy.
