3.3.15 Resolving forces for advanced problems (A-level only)

For a mass mmm on a plane inclined at lpha, which weight component acts down the plane?

A

For sliding or limiting friction, F=μR\boxed{F=\mu R}F=μR​; in static equilibrium, 0≤F≤μR0\le F\le\mu R0≤F≤μR.

B

Tension is an internal force acting oppositely on the particles.

C

For sliding or limiting friction, F=μRF=\mu RF=μR; in static equilibrium, 0≤F≤μR\boxed{0\le F\le\mu R}0≤F≤μR​.

D

mgsin⁡αmg\sin\alphamgsinα
