Statics

Force moment, lever

$$M = F\cdot d$$

F - force
M - force moment
d - distance (arm of force)

Find It is known that:

$$d = r\cdot sin(a)$$

d - arm of force
r - radius

Find It is known that:

$$\frac{F1}{F2} = \frac{d2}{d1}$$

F1, F2 - forces
d1, d2 - arms of force

Find It is known that:

Inertia moment of rotating body

$$J = m\cdot r^{2}$$

J - inertia moment
m - mass
r - radius

Find It is known that:

$$p = \frac{F}{S}$$

p - pressure
F - force
S - area

Find It is known that:
