What is the tension force of the cable of the crane, if, with a uniform lifting of the load by 10 meters, this force has done a work of 10 kJ.
To find the magnitude of the tension force of the cable of the specified crane, we apply the formula: A = F * S = N * S, from where we express: N = A / S.
The values of the variables: A – the work done by the tensile force (A = 10 kJ = 10 ^ 4 J); S – movement of the load (S = 10 m).
Calculation: N = A / S = 10 ^ 4/10 = 103 = 1 kN.
Answer: The tension force of the cable of the indicated crane was 1 kN.
