An electric motor running at 970rpm is used to drive a rock crushing machine with a design power of 32 kW. A 33oz ducking weight flat belt drive is proposed with a tension ratio of R = 4 and belt width b = 120 mm. The pitch diameter of the driving pulley (on the motor-end) is 320mm. a) What is the mass per mm width per m length per ply in kg/mm/m/ply? Number (exact value) b) What is the maximum working tension per mm width per ply in N/mm/ply? Number (exact value) c) Calculate the belt velocity in m/s Number (+/-1%)

A mini motorcycle is driven by a combustion engine with mechanical transmission. The 12Hp motor spins at a speed of 1150 rpm. The motorcycle runs at a linear speed of 45 km/h on 12-inch wheels. Preliminary center to center distance is 13”. This type of motorcycle requires two strands (conical double sleeve assembly) and is subjected to hard shocks. Can I get a detailed explanation for Choice of chain and sprocket. (Standard part number, see catalog) https://pdf.directindustry.com/pdf/martin-sprocket-gear/general-catalog/9091-246439.html
