- If the given forces P₁, P₂, P₃ and P₄ are such that the force polygon does not close, then the system will
- A shell travelling with a horizontal velocity of 100 m/sec explodes and splits into two parts, one of mass 10 kg and the other of 15 kg. The 15 kg mass drops vertically downward with initial velocity of 100 m/sec and the 10 kg mass begins to travel at an angle to the horizontal of tan”1 x, where x is
- A ladder of weight 'w' rests against a smooth vertical wall, and rests on rough horizontal ground, the coefficient of friction between the ladder and the ground being 1/4. The maximum angle of inclination of the ladder to the vertical, if a man of weight 'w' is to walk to the top of it safely, is tan'1 x, where x is
- For a simple pendulum, the period of one oscillation is
- The locus of the instantaneous centre of a moving rigid body, is
- The inherent property of a body which offers reluctance to change its state of rest or uniform motion, is
- Engineer's units of force, is
- If y is force and x is velocity, then dimensions of —=r are dx2
- The moment of inertia of a hollow circular section whose external diameter is 8 cm and internal diameter is 6 cm, about centroidal axis, is
