Calculating Acceleration and Torque Required in an Output Shaft
Hello All,
I am learning Engineering Science at a college in England. One of my assignment questions asks me to calculate the torque required to accelerate a hollow shaft from 500rpm to 3600rpm in 2.4 secs. The shaft is 1.8kg and 0.65m in length. 45mm diameter and 4mm wall thickness.
I worked the above figures into T=mar[SUP]2[/SUP], where a is the angular acceleration (don't know how to do the Greek symbol) and got a worryingly small answer of 0.12 Nm. It might be my lack of experience with these calculations or I might be missing something, but it doesn't feel right. I'm just hoping for a few helpful comments
