- According to Lami's theorem
- Which one of the following statements is not correct
- A single force and a couple acting in the same plane upon a rigid body
- If a suspended body is struck at the centre of percussion, then the pressure on die axis passing through the point of suspension will be
- Center of gravity of a solid cone lies on the axis at the height
- A semi-circular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi-cricular disc and horizontal surface is i. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will

A.
Three forces acting at a point will be in equilibrium |
|
B.
Three forces acting at a point can be represented by a triangle, each side being proportional to force |
|
C.
If three forces acting upon a particle are represented in magnitude and direction by the sides of a triangle, taken in order, they will be in equilibrium |
|
D.
If three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two |
