Static Equilibrium - Tension, Torque, Lever, Beam, & Ladder Problem - Physics

Define torque, and state the conditions necessary for stable equilibrium.

Static Equilibrium

For an object to be in equilibrium ___________Group of answer choicesthe resultant force on it must be zeroneither the resultant force nor the resultant torque needs to be zerothe resultant torque on it must be zeroboth the resultant force and the resultant torque need to be zero

Write the necessary equations of equilibrium of the object shown in the figure below. Take the origin of the torque equation about an axis perpendicular to the page through the point O. (Let counterclockwise torque be positive and let forces to the right and up be positive. Use the following as necessary: the forces Rx, Ry, Fx, Fy, and Fg; the length ℓ of the object; and the angle 𝜃 that the object makes with the horizontal.)A rod of length ℓ makes an acute angle 𝜃 clockwise from the horizontal. A point at the left end of the rod is labeled O. Five forces act on the rod as follows.A force with magnitude Rx begins at the left end of the rod and points horizontally left.A force with magnitude Ry begins at the left end of the rod and points vertically up.A force vector Fg begins at the center of the rod and points vertically down.A force with magnitude Fx begins at the right end of the rod and points horizontally right.A force with magnitude Fy begins at the right end of the rod and points vertically up.ΣFx = = 0ΣFy = = 0Σ𝜏 = 0 = 0
