How to Evaluate Torque Expression 3540 mm × 45.0 kN?

What is the torque value of the expression 3540 mm × 45.0 kN?

a. 159kNm
b. 1.59×10⁵ kNmm
c. 1.59×10⁸ Nmm
d. any of the above

Answer:

The torque is 1.59 × 10⁵ kN mm. Hence, the answer is option (b).

To evaluate the given expression 3540 mm × 45.0 kN, we use the formula of torque, which is Torque = Force × Distance. Since the given expression involves force and distance, it is a torque expression. Therefore, we apply the formula and obtain the value of torque as follows:

Torque = Force × Distance = 3540 mm × 45.0 kN = 1.59 × 10⁵ kN mm

Therefore, the value of the given expression is 1.59 × 10⁵ kN mm. Thus, the torque is 1.59 × 10⁵ kN mm. Hence, the answer is option (b).
