A heavy concrete panel is being lifted into position in a building by means of a crane (see figure below). The tension of 1.02 x 104 N in the supporting cable produces a torque with respect to point O. (Let L = 17.9 m.)   (a) Does this torque tend to rotate the panel clockwise or counterclockwise about an axis through point O? clockwise or counterclockwise

Question

A heavy concrete panel is being lifted into position in a building by means of a crane (see figure below). The tension of 1.02 x 104 N in the supporting cable produces a torque with respect to point O. (Let L = 17.9 m.)

 
(a) Does this torque tend to rotate the panel clockwise or counterclockwise about an axis through point O?
clockwise or counterclockwise    

(b) Find the torque.
The image depicts a mechanical scenario involving a uniform rod of length \( L \) leaning against a vertical support, such as a wall. The lower end of the rod rests on the horizontal ground. Key features of the diagram include: - The rod is shown to form an angle of \( 53.0^\circ \) with the horizontal ground. - A tension force \( T \) is indicated at the top end of the rod, pulling towards the wall. - A coordinate system is included, with the origin \( O \) at the point where the rod touches the ground. The \( x \)-axis extends horizontally along the ground, and the \( y \)-axis extends vertically upwards. This setup is common in physics problems related to statics and equilibrium, where forces like tension, gravity, and normal force must be analyzed.
