p≤ p A

where:

	T	torque [lb ft]
	d	small shaft diameter [in].
	D	greater shaft diameter [in].
	p	contact pressure in a joint [psi]
	p_A	allowable pressure [psi]
	L	hub length [in]
	υ	clamping factor υ = 0.008 to 0.1 [-]
	k_s	slip safety [-]
	F	force carried by one bolt [lb]
	φ	friction angle φ = arctg υ.
