Final answer:
The brake torque can be calculated using the formula Torque = Radius x Force x Friction Coefficient. Substituting the given values, the brake torque comes out to be approximately 18.486 Nm.
Step-by-step explanation:
To calculate the brake torque, we need to use the formula: Torque = Radius x Force x Friction Coefficient. In this case, the contact area and the working pressure do not directly affect the torque calculation. Therefore, the brake torque can be calculated as follows:
Torque = (0.150 m) x (0.017 m x 324 N/dm²) x (1.5 N x 0.5 Pa.s)
Calculating the above expression gives a brake torque of approximately 18.486 Nm.
