The Basics of Limit Switches
The lever arms may be rod or roller types in various fixed or adjusta-ble lengths, and made from various materials and sizes of rollers. Lever actuators are usually the best choice for the majority of applications and are suitable for actuation by any cam whose motion is perpendicular to the shaft axis about which the lever rotates.

UNIT 8 STRESS DISTRIBUTION
2006-9-19 · The vertical stress is given by: σz = 3P 2π z3 R5 = 3P 2πR2 cos3 β = I P z2 (8.1) where I is termed an influence factor. One of the several reasons for assuming that the soil consolidates in response to the change in vertical stress is the relative simplicity of the equations, which do not contain Poisson''s ratio.
