WebHolding Torque for a Brake Application. In certain applications, mounting a brake on an arm will hold a load from falling in the event that power fails or is removed. For these instances, determining load torque requires the holding torque and the weight of the arm (force x distance) multiplied by a service factor of 1.5. Here are the variables: WebStep 2 – express the holding capacity as a moment; M = X1 HC1 = 49,5mm x 4450N = 220275 N mm. Step 3 – calculate the holding capacity at XC; HC = M ÷ Xc = 220275 ÷ …
