Three forces acting on a body

Four forces are acting on a body as shown in figure. The magnitude of resultant of the forces is. Find the magnitude of the resultant of shown forces Two forces, each equal to F, act as shown in figure Their resultant is. A force F is acted on a body as shown in the figure. Find the impulse of the force in first four seconds. Three forces are acting on a body to make it in equilibrium , which set can not do it? Two forces of 4 dyne and 3 dyne act upon a body. The resultant force on the body can only be —. If the external forces acting on a system have zero resultant, the centre of mass. There exists a uniform magnetic field of magnitude B along one of the sides of cube.

Three forces acting on a body are shown in the figure. To have the resultant force only along the y-direction, the magnitude of the minimum additional force needed is -. In order to bring Net force along only Y-axis, the net force along X-axis should be equal to zero. So, 0. Important Points. Get Started.

An important quantity for describing the dynamics of a rotating rigid body is torque. We see the application of torque in many ways in our world. We all have an intuition about torque, as when we use a large wrench to unscrew a stubborn bolt. Torque is at work in unseen ways, as when we press on the accelerator in a car, causing the engine to put additional torque on the drive train. Or every time we move our bodies from a standing position, we apply a torque to our limbs. In this section, we define torque and make an argument for the equation for calculating torque for a rigid body with fixed-axis rotation. So far we have defined many variables that are rotational equivalents to their translational counterparts. Since forces change the translational motion of objects, the rotational counterpart must be related to changing the rotational motion of an object about an axis.

We say that a rigid body is in equilibrium when both its linear and angular acceleration are zero relative to an inertial frame of reference. This means that a body in equilibrium can be moving, but if so, its linear and angular velocities must be constant. We say that a rigid body is in static equilibrium when it is at rest in our selected frame of reference. Notice that the distinction between the state of rest and a state of uniform motion is artificial—that is, an object may be at rest in our selected frame of reference, yet to an observer moving at constant velocity relative to our frame, the same object appears to be in uniform motion with constant velocity. Because the motion is relative , what is in static equilibrium to us is in dynamic equilibrium to the moving observer, and vice versa. Since the laws of physics are identical for all inertial reference frames, in an inertial frame of reference, there is no distinction between static equilibrium and equilibrium. In equilibrium, the linear acceleration is zero. The first equilibrium condition for the static equilibrium of a rigid body expresses translational equilibrium:. This vector equation is equivalent to the following three scalar equations for the components of the net force:.
