b) Impending motion is the moment where the body is on the verge of slipping. Static friction force reaches the max value. For a given pair of mating surfaces,.


Next it says you can only consider that if there is impending motion. Then it says with no apparent impending motion, you can't use this.


This equation only gives the force of friction when motion is impending. If motion is not impending, then the friction force, fs, will be less than the maximum, or.


... friction forces exceeds the moment exerted by the gravity and normal forces. For impending motion the normal force will be acting at the very edge of the body.


P-508 has impending motion up the plane caused by the horizontal force of 400 lb. Determine the coefficient of static friction between the contact surfaces.


\(M=rWtan(\theta+\phi)\) For downward impending motion where theta is greater than phi, I use the same equation as above, but instead of rWtan(theta + phi), ...


Static Friction (Impending Motion) impending motion-the case where motion is " imminent” such that the. Fiction Force, F attains a certain Maximum value, Fs.


Problem 540. As shown in Fig. P-540, two blocks each weighing 20 kN and resting on a horizontal surface, are to be pushed apart by a 30° wedge. The angle of ...
