What is the formula for calculating weight using a mild steel cylinder?
gear with shaft dia40mm length 230 teeth 14 shaft dia 25mm width 6.5mm length 168mm
Calculation for weight of steel. Volume of Steel Rod(Vs)= (pi*d*d)/4*l.where pi= 3.14 d Diameter of bra= 8 mm in this case l length of bar = 1 m so, Volume of steel = ((3.14*0.008*0.008)/4)*1 =0.00005024 m3 Weight of steel = volume of steel * unit weight of steel Unit weight of steel = 7850 kg/m3 Weight of steel = 0.00005024* 7850 = 0.394 kg/m
If you are asking about a scuba cylinder, aluminum is less expensive than steel and it will not rust. However it is a softer metal so it can scratch or get deep gouges where steel will not. Since it is a softer metal, it requires more metal to hold pressure so an aluminum tank is actually heavier out of the water ... and less negative in the water which will require a diver to wear…
