The drive from a motor to a machine is by means of a crossed flat belt. The shat of the motor and the machine are parallel and 1.2 meter apart. The motor pulley A turns at 1440rpm and has a diameter of 250mm. The machine B rotates at 450rpm. The belt is made of lether. The safe tensile stress is 7MPA and the density is 900kg/m. The dimensions of the belt are 50mm x 6mm. u = 0.2. Dermine: i) The length of the belt required ii) The maximum power that can be transmitted The maximum torque on the driving pulley iv) The maximum torque on the driven pulley

Question
The drive from a motor to a machine is by means of a crossed flat belt. The shat of
the motor and the machine are parallel and 1.2 meter apart. The motor pulley A turns
at 1440rpm and has a diameter of 250mm. The machine B rotates at 450rpm.
The belt is made of lether. The safe tensile stress is 7MPA and the density is
900kg/m. The dimensions of the belt are 50mm x 6mm. µ = 0.2.
Dermine:
The length of the belt required
The maximum power that can be transmitted
The maximum torque on the driving pulley
The maximum torque on the driven pulley
