Hand-Operated Hydraulic Pump

Force versus

temperature

The following figure shows that the grip force rating for specimen temperatures

up to 700°C is 67 kN (1292°F at 15,000 lb) is stable. The figure also shows that

the force rating is reduced proportionately for specimen temperatures between

700°C and 1000°C (1292°F and 1832°F), with a maximum force rating of 8.9 kN

at 1000°C (2000 lb at 1832°F).

Grip Force Rating versus Specimen Temperature

Force versus hydraulic

pressure

The horizontal scale at the bottom of the graph shows required gripping pressure

versus maximum force to be applied, which is shown on the left hand vertical

scale.

The right hand vertical scale is provided as a convenience. Assuming that the

gage portion of the specimen has a diameter of 0.25 inches, the right hand scale

shows maximum engineering stress (for a 0.25 inch diameter specimen), versus

required gripping pressure on the bottom horizontal scale and also the equivalent

force on the left hand vertical scale.
