Three forces acting on a body

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. SSC Exams. Banking Exams. Teaching Exams. Civil Services Exam.

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?

A very basic concept when dealing with forces is the idea of equilibrium or balance. In general, an object can be acted on by several forces at the same time. A force is a vector quantity which means that it has both a magnitude and a direction associated with it. Two forces with the same magnitude but different directions are not equal forces. The vector sum of all of the forces acting on a body is a single force called the net force. If the net force is equal to zero, the object is said to be in equilibrium. Because there is no net force acting on an object in equilibrium, then from Newton's first law of motion, the object continues to move at a constant speed. On another page, we show the simplest example of equilibrium with two forces acting on an object.

Three forces acting on a body

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.
