  1. Q3 Pushing or pulling vehicle with same magnitude of force along the same line of action is called as Principle of transmissibility The area under the speed.-time graph gives the Distance travelled by the particle Velocity of the particle Acceleration of the particle Momentum of particle Which of the following statements describes the resultant of two forces? Force that maintains the system in equilibrium Force that has the highest magnitude in the system Force that has the same effect as the two forces Force that has the same effect as one force s , then the height of the building is (ignoring air resistance) (g = 9.8 is a free-body Option A: It’s a sketch of a moving body that shows internal forces of the body and reaction
  2. Q10 Which of the following doesn’t affect frictional force?
  3. Q2 Solve any four questions out of six 5 marks each Replace the following force system by a force couple system (i) at point A. (ii) at If a horizontal force of 1200 N is applied to block of 1000 N, then block will be held in equilibrium or slide down or move up? Take c A heavy roller with radius 14 cm and weighing 2000 N is pulled to the right by a pulling acting angle with respect to horizontal as shown in figure A step stops the rolling motion of the roller. Find the magnitude of force T, to just start the motion of the roller At the instant shown in the figure, the rod AB is rotating clockwise at 2.5 rad/sec If the end C of the rod BC is free to move on a horizontal surface find the angular velocity of rod BC and the velocity of its end point C e A particle moves in a circular path of calculate after 4 seconds: the particles total acceleration and distance travelled if speed is constant at f Locate the centroid of the shaded area w.r.t “O’
