a block of mass 2.50 kg rests on a ramp. if the coefficient of static friction between the block and the ramp is 0.350, what is the maximum angle the ramp can make with the horizontal before the block begins to slide? F=2.50*9.8=24.5N@A deg.
Fp = 24.5*sinA = Force parallel to the plane.
Fv = 24.5*cosA = Force perpendicular to
plane.
uFv = 0.35Fv = Friction force.
Fp – 0.35Fv = ma,
a = 0(block at rest),
Fp-0.35Fv=0,
Fp = 0.35Fv,
24.5*sinA = 0.35*24.5*cosA,
Divide both sides by 24.5:
sinA = 0.35*cosA
Divide both sides by cosA:
sinA / cosA = 0.35,
sinA / cosA = TanA,
TanA = 0.35,
A = 19.3 degrees. answer show me the steps of the calculation until the final answer Meaning of fv,fp Fp and fv their meanings
