Horizontal motion of the piston rod of the hydraulic cylinder controls the rotation of link ob about o. for the instant represented, va = 3.1 m/s and ob is horizontal. determine the angular velocity ωob (positive if counterclockwise, negative if clockwise) of ob for this instant. solve for the angular velocity of ob by the method of this article.

like poles repel so keep pushing north to north and repels funny to see this

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
