Homework Statement
Example (Block on a plane): A block of mass M rests on a fixed plane inclined
at angle theta. You apply a horizontal force of Mg on the block, as shown in figure 1-1 (attached). The free-body diagram for this is also attached as an image.
Assume that the friction force between the block and the plane is large enough
to keep the block at rest. What are the normal and friction forces (call them N
and F_f) that the plane exerts on the block?
Homework Equations
Just the use of basic statics?
Also trigonometric expressions involving sin and cos
The Attempt at a Solution
I initially try to find F_f itself by drawing the vector connection the heads of F_f and the Mg applied force (as shown in the free-body diagram).
However, I cannot find F_f this way.
I think there is something I am missing while trying to balance the forces.
