Ex: 1 Elevator- The elevator’s Force Weight- Fw- 500kg x 9.8m/s^2 = 4900N
Using and understaiding forces is the basis for all things related to moving objects. From this page you will learn about these 4 basic forces. This is used all over the world more notablyin elevator technology, as well as in rocket technology. Force is measured in Newtons of force.
Ex: 2 Weight on an incline
Force Normal-Fn= cos(40)x Fw = 189NThe friction Coef. Can range from 0(smooth) to 1(rough)
M=.3 Force Friction-Ff
Force Friction = The Friction
Coefficient x ForceNormal .3 x 189N = 56.7N
Fa- Ff = Net force
In problems to solve for the force of a system do as in Example 2 for each side and subtract from each other and that is the net force. The direction of the system goes toward the side with greater force. These problems rleate to basic pully sysmems where the applacations are ulimited
Static Equilibrium
Solve the two equations Simultaneously
F1cos(Ø) – F2 cos(Ø) = 0 - Ft sin(Ø) + Ft sin(Ø)=
