# Inclined-plane force
# Scope: Quasistatic upward pull with Coulomb sliding friction.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

mass = 10 kg
angle = 15 deg
friction = 0.2
gravity = 9.81 m/s^2

normal := mass*gravity*cos(angle) [N]
pull := mass*gravity*sin(angle)+friction*normal [N]

check pull budget: pull <= 60 N

scenario alternative: mass = 8 kg
