How to find the maximum tension on a belt in a belt drive

belt cross sectional area 1000mm^2 Wl = Weight of Load on Belt (lbs per sq. ft.) L = Conveyor Length (ft.) (1/2 the belt length) 2. Calculate the drive tension per width of belt by taking the Td figure found in step 1 and dividing by the belt width. If using a belt at an elevated temperature, multiply the maximum allowable tension per
