magnetic force on the proton is F = qv × B where q = +e . Using Eq. 3-30 this becomes (4 × 10−17 )i + (2 × 10−17)j = e[(0.03vy + 40)i + (20 – 0.03vx)j – (0.02vx + 0.01vy)k] ^ ^ ^ ^ with SI units understood.

normal force of the ground on the player, mg is the force of gravity, and f is the force of friction. The force of friction is related to the normal force by f =  kFN. We use Newton’s second law applied to the vertical axis to find the normal force. The vertical component of the acceleration is zero, so we obtain FN – mg = 0; thus, FN = mg.

stress failure and the corresponding stress components acting at those locations must be identified. Once all the stress components at a given location are determined, they may then be combined to find principal stresses, maximum shear stress or other measures that are useful for predicting design success or failure. It is very important to remember that stress components for one location in a machine part should never be combined with stress components for a different location in…
