Fundamental

Simply Supported Beam Reaction (Point Load)

R1 = (F * b) / L

Fundamental

Static Friction Force

F_f = mu_s * N

Fundamental

Center of Gravity (Two Point Masses)

x_cg = (m1*x1 + m2*x2) / (m1 + m2)

Fundamental

Resultant of Two Forces

R = sqrt(F1^2 + F2^2 + 2*F1*F2*cos(theta))

Fundamental

Moment of a Force (Torque)

M = F * d

Fundamental

Stress

σ = F / A
