Steel Shafts
Steel Shafts
A hollow steel shaft with external diameter 150 mm is required to transmit 1MW at 300 rpm?
Calculate a suitable internal diameter
for the shaft if its shear stress is not to
exceed 70 MPa. Compare the torque
carrying capacity of this shaft with a solid
steel shaft having the same weight per unit
length and limiting shear stress. Take G = 80
GPa.
*P=2*Pi*N*T / 60
P in watt
N=RPM
T in N-m
1 megawatt = 1 000 000 watt
T=P*60 / 2*Pi*N
T=1 000 000 * 60 / 2*3.14*300
T=31847.134 N-m
Here, the torque is mean.
Tmax =1.2 * Tmean
Tmax =1.2 * 31847.134
Tmax =38216.5608 N-m
Tmax =38216.5608*1000 N-mm
For hollow shaft , max torque transmitted is given by,
[3.14/16] * shear stress * [(Do^4 - Di^4)/Do]
=0.19625*70* [(Do^4 - Di^4)/Do]
[1 megapascal = 1 newton/square millimeter]
38216.5608*1000/13.7375 = [(Do^4 - Di^4)/Do]
2781915.254 = [(Do^4 - Di^4)/Do]
2781915.254 *Do=Do^4 - Di^4
417287288.1 = 506250000 - Di^4
Di^4 = 506250000 - 417287288.1
Di^4=88962711.9 mm
Di = 97.1185 mm is the internal diameter of a hollow shaft.
*torque/polar moment of inertia = modulus of rigidity * theta / Length= shear stress / radius.
polar moment of inertia = [3.14 / 32]*D^4 for solid shaft
polar moment of inertia = [3.14 / 32]*[Do^4- Di^4] for solid shaft
equate the equation for hollow shaft and solid shaft as the length is same.

Who says an advanced game improvement model can't look conventional? While it does feature a moderate topline, reduced offset and classic profile at address, the secret is in the sole and rear cavity mass stabilizing bar. Enhanced perimeter weighting and wider, thicker sole focuses weight where it is needed for most golfers to experience a higher ball flight, a more solid feel and with precision accuracy. Put some muscle between you and the ball and fire away in confidence.
Big, bad and bold are just some of the words to describe this powerful new iron design. The precision cast 431 stainless steel outer shell creates the foundation by optimizing the deep, rear center of gravity location for the extremely high moment of inertia resulting in superior accuracy and a driving trajectory. It is joined together with a separate high-performance face plate formed by an ultra-thin sheet of high strength 420 specialty maraging steel. This translates into a more explosive ball velocity coming off of the face for the ultimate in distance. From the ultra-wide beveled sole and heavy rear mass to the unique appearance at address, the Caiman Irons put more raw power in your hands to produce shots that you only dreamed of.
The modern design and improved technology have made the Power Play Caiman Irons some of the most sought after Golf Irons of the day. Golfers around the world are raving about these New Caiman Irons!
