A heavy concrete panel is being lifted into position in a building by means of a crane (see figure below). The tension of 1.89 104 N in the supporting cable produces a torque with respect to point O. (Let L = 39.3 m.)
(b) Find the torque.
torque = force•arm of the force =
=1.89•10^4•39.3=7.43•10^5 N•m
To find the torque produced by the tension in the supporting cable, we can use the formula:
Torque = Tension * Distance
Given:
Tension (T) = 1.89 * 10^4 N
Distance (L) = 39.3 m
Plugging in the values, we can calculate the torque:
Torque = 1.89 * 10^4 N * 39.3 m
Torque = 7.437 * 10^5 N m
Therefore, the torque produced by the tension in the supporting cable is 7.437 * 10^5 N m.
To find the torque produced by the tension in the supporting cable, we can use the formula:
Torque = Force * Distance
In this case, the force is the tension in the cable (1.89 x 10^4 N) and the distance is the distance between the point of rotation (point O) and the point where the force is applied (the location of the concrete panel). The distance is given as 39.3 m (L).
Therefore, the torque can be calculated as follows:
Torque = Force * Distance
= (1.89 x 10^4 N) * (39.3 m)
= 7.44 x 10^5 N*m
So, the torque produced by the tension in the supporting cable is 7.44 x 10^5 N*m.
