STATICS

STATICS. When static??. When a method’s behaviors has no dependency on state of an object i.e.., when the method will never be instance specific. E.g.., A class having a method which generates random number

STATICS OF PARTICLES

STATICS OF PARTICLES. Forces are vector quantities ; they add according to the parallelogram law. The magnitude and direction of the resultant R of two forces P and Q can be determined either graphically or by trigonometry. R. P. A. Q.

Statics

Statics. Static Equilibrium. There are three conditions for static equilibrium. The object is at rest There is no net force There is no net torque. With no motion, forces must sum to zero. Each component is treated separately. Find the tension in the ropes. T is the tension to the left

Statics

Statics. Chaper 5 Friction. Intro. Two surfaces are in contact – forces tangent to the contact surfaces – known as friction forces – always exist if a surface has a tendency to slide on another surface, or two surfaces are actually in sliding contact Two main types of friction Dry friction

Statics

Statics. Static Equilibrium. There are three conditions for static equilibrium. The object is at rest There is no net force There is no net torque. Offset Forces. Balanced forces do not insure static equilibrium. The center of mass is stationary, but the object rotates. F. -F.

Statics

Statics. Chapter 1. Introduction to Statics. What is Statics?. Statics is the study of systems in which the motion of the object is not changing (no acceleration) Static – Not Changing Equilibrium – No net force, zero acceleration. 0. What is systems is Statics used to describe or analyze?.
