A motorized pulley of diameter 200 mm is used to transfer a block of mass 100 kg from platform 1 to platform 2 using a ramp kept at an inclination of 30° as shown in the figure. The coefficient of static friction between the block and the ramp is 0.2. The acceleration due to gravity is 10 m/s2. Assume the rope to be parallel to the ramp surface. The minimum torque required by the motor to transport the block uphill is ____ Nm (rounded off to two decimal places). Figure is not to scale
