  2. As a verb, affect means to influence ("Smoking may affect your health") or to adopt a pose or manner ("She affected ignorance"). Effect as a verb means to accomplish ("The prisoners effected an escape"). As a noun, the word needed is almost always effect (as in "personal effects" or "the damaging effects of war").

    RE: Question on use of affect/effect affecting/effecting chicopee (Mechanical) 3 Mar 12 17:44 I love the English language as it can be molded, twisted, stretched to make any sentence to portrait an idea.

    In effect, the wear ring or bushing becomes a stable bearing. This reduces the chance of a rub, even with a flexible rotor. When you change to Vespel, you will run tighter clearances. This increases the Lomakin affect and the rotor is even more stable and likely to stay close to the center of the clearances.

    Recommended for you. "End cap effect", or "closed end effect" is due to internal pressure acting on (virtual) plates assumed to be on each end of a pipe segment such that internal pressure (P) is contained. "End cap force" is thus equal to pressure x plate area, or P * pi * D^2/4, D being diameter, and causes axial tension on the pipe. It is ...

  6. CoryPad (Materials)21 Jan 04 11:33. Yes, the washer material affects the results when torquing a bolt. During torquing, a reaction torque exists between the bolt and the washer. The magnitude of the reaction torque is a function of the friction coefficient. The friction coefficient is material dependent.

  7. Effect of Heat on Structural Steel - Eng-Tips

    You should also consider the effect of heat on the steel modulus. The modulus of elasticity and or Young's modulus is also dependent on temperature. Recall that both deflection and buckling equations are based on the Modulus. As a result, you could have a displacement or buckling failure prior to reaching a failure via normal or shear stress.

  8. Sure - scrub radius has an effect on steering effort. Two reasons come to mind: 1. Scrub radius is the lever arm that transfers longitudinal forces acting on the contact patch (es) back to the steering wheel. This is the source of "torque steer" in FWD vehicles and a similar effect during braking with unequal mu. 2.

  9. The affect of annealing on Permeability - Eng-Tips

    The effect of the annealing is going to vary tremendously depending on the condition of the unannealed material. In my case I think it was cold drawn bar so heavily cold worked. The Help for this program was created in Windows Help format, which depends on a feature that isn't included in this version of Windows.

  10. Density Effect on Pump Power and Load - Eng-Tips

    1/ effect of specific gravity on pump discharge pressure (as the pump head in independant of density). A higher density means a higher pump differential pressure and thus a higher discharge pressure. 2/ effect of valve opening on discharge pressure. Indeed, when the valve opens, the valve pressure drop decreases and, as a result the pump ...

  11. Internal pressure can affect the pipe bend or elbow in 2 ways. The Bourdon effect describes the tendency for the pipe bend to "open" under internal pressure and "close" under external pressure. The reason is as described by Electricpete. The other effect is the "stiffening" of pipe bends and elbows as internal pressure is increased.
