If a hollow tapered shaft and a sleeve is designed to be fitted, by thermally expanding the sleeve and cold shrink fitting the hollow shaft with dry ice, can the item be assembled or dissembled by pressure alone?
I have been told that such assemblies can be disassembled without temperature...
I have a hydraulic jack with an 8 inch diameter piston. This means the surface area of piston head is about 50.25 sq. Inches. If I apply 10,000 psi with a hydraulic pump then the force that this jack can lift is about 251.2 Tons.
F= P*A
251.2 = 10,000 psi * 50.25
I understand that this holds...
What is the best way to calculate Impact Force per Blow given a jackhammer's weight, BPM (Blows per Minute), and Stroke Length? For ,example Ingersoll Rand JH40C3 has a Stroke Length of 67mm, BPM of 2000, and a weight of 27.7 kg.
I was thinking to use F=(0.5MV^2)/2 or F=(MV)/T ,but I am...
