... the air while the inertia of the head causes it to lag. This motion puts a large bending moment on the hosel. As the swing continues, the golfer’s hands decelerate. The club head’s inertia then pushes it ahead of the shaft, reversing the load on the hosel. The magnitude of the reversal is larger than...

... manufacturing industry has been to add compensating balance weights as shown in Figs. 4 and 5 . The object in adding the weights is to align the axis of rotation of the roll with its principle axis of inertia. The principle axis of inertia of a body, such as this roll, is a function of its mass distribution...

As a result, the overall load at the fracture-critical location in a spin-pit simulation test is lower than that which is operative during service. The aircraft...
