# 313 Maximum Torque That Can be Applied to a Hollow Steel Shaft

### Based on maximum allowable

Based on maximum allowable angle of twist:

where did you get the value of L?
im still confuse about the value of L being 1000

### The maximum allowable twist

The maximum allowable twist is 0.5 deg/meter, that is, 0.5 degree for every L = 1 meter length.

### if u see here 0.5 degree per

if u see here 0.5 degree per meter given,but we have to calculate mm unit thats why here 1000 multiplied

### how is MPa got canceled by mm

how is MPa got canceled by mm?

### Note: 1 MPa = 1 MN/m2 = 1 N

Note: 1 MPa = 1 MN/m2 = 1 N/mm2.
