Final answer:
To find the tension in the belt when the motor is off, you can use the concept of pulleys. In this scenario, if the pulleys are friction-free, the force output is approximately an integral multiple of the tension in the cable. Since each attachment applies an external force in approximately the same direction, they add up, producing a total force nearly a multiple of the input force T.
Step-by-step explanation:
In the given question, there are two v-belt pulleys, and pulley A receives power from a motor through a belt with belt tensions T1 and T2. To find the tension in the belt when the motor is off, we need to consider the weight of the motor and platform. When the motor is not running, the tensions T1 and T2 are equal.
The total mass of the platform and motor is 100.0 kg, and the diameter of the drive belt pulley is 16.0 cm. In this scenario, we can use the concept of pulleys to determine the tension in the belt. If the pulleys are friction-free, the force output is approximately an integral multiple of the tension in the cable. Since each attachment applies an external force in approximately the same direction, they add up, producing a total force nearly a multiple of the input force T.
