- What is the Design procedure in Determining the number of V-belts required?arrow_forwardWhich of the following statements about drive belt slippage is not true? Excessive heat normally comes from slippage. As a V-belt slips, it begins to ride deeper in the pulley groove. Slippage can be caused by improper belt tension or oily conditions. When there is slippage, heat travels through the drive pulley and down the shaft to the support bearing of the component it is driving.arrow_forward2.
