Practice FE Mechanical Statics in the app →A beam sits still under several forces. The first condition it must satisfy concerns the forces on it, and theAll the forces on a small object act along the axis of rotation, so every torque is zero. Only one condition sBoth equilibrium conditions are stated with respect to something the engineer must fix first. That is a:The origin of the chosen reference frame, about which torques are taken, is called the:Before writing equilibrium equations for a rigid body, an engineer should first draw a:On such a diagram, the weight vector is attached at the:For practical purposes, that point coincides with another familiar point. That other point is the:The two points separate only when a body is so large that the gravitational field across it is:In the torque equation, the perpendicular distance from the pivot to the line of the force is the:A box tips slightly but its center of gravity stays over its base, so gravity turns it back. That position is Two terms describe forces on a deforming object. One is strain and the other is:Stress is generally defined as force divided by:An engineer reports a stress figure in SI units. Those units are:Strain is reported as a fractional change in length, volume or geometry. That makes strain:An elastic band is pulled and stretches longer. The stress applied to it is:A column carries a load that squeezes it shorter. The stress in it is:A diver deep underwater is squeezed equally from every side. That kind of stress is also known as:The elastic modulus for tensile stress carries a name of its own. It is:The tendency of a solid to return to its original shape once the load is removed is called:Two parameters together fix how elastic a material is: its elastic modulus and its elastic:Within the linear range, the stress-strain relation is described by analogy with the law that governs a springTwo materials carry the same stress, but one has a much larger elastic modulus. In that one, the deformation i
