forces and are acting parallel to the length and base of an inclined plane respectively would each of them singly support a weight , on the plane, then
Step 1. Given data
Two forces and are acting parallel to the length and base of the inclined plane.
Step 2. Finding the force,
By using the Lami 's theorem
According to this theorem, if three concurrent forces act on a body keeping it in Equilibrium, the each force is proportional to the sine of the angle between the other two forces.
Now, Case - When force is acting
Using Lami's theorem, we get
[Where, is weight, is the reaction]
[] []
Step 3. Finding the force,
Now, Case - When force is acting
Again, using Lami's theorem
[]
[] []
Now, value of
[from ]
[]
[]
Hence, the correct option is .
