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

Which of the following is a condition for a body to be in equilibrium when acted upon by a set of coplanar forces?*1 pointThe forces must be reasonably largeThe net torque on the body must be zeroThe masses acting on the body must be equalNone of the above

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

If an object is in equilibrium, which of the following statements is not true?     2 pointsThe object must be at rest.There are at least two forces acting on the object.The acceleration of the object is zero.The net force acting on the object is zero.The speed of the object remains constant.

The condition of translational equilibrium states that the vector sum of all the forces acting on an object in equilibrium is zeroGroup of answer choicesTrueFalse

What is equilibrium?when there are no forceswhen an object does not movewhen all forces acting on an object remain the samewhen the forces acting on an object change
