Chapter 01: Basic Physics for the Respiratory Therapist 
MULTIPLE CHOICE 
1. Power is a measure of which of the following? 
a. Mechanical energy 
b. Gravitational potential energy 
c. The rate at which work is being performed 
d. The rate at which atoms and molecules move 
ANS: C 
Power is a measure of the rate at which work is being performed. The formula P = W/J, where 
W = watts and 1 watt is equal to 1 J/s, expresses this. Joules are the international standard for 
expressing energy and work...

Equilibrium 
 
 
 
 
 
of a rigid body 
 
 
 
Objectives 
•	To demonstrate how 2-D equations of equilibrium apply to a rigid-body (in which not all forces converge at a point) 
 
•	To practice drawing free-body diagrams 
 
•	To identify two-force members 
 
 
 
 
 
 
 
We can use ‘equilibrium at a point’ to determine the cable forces 
Fx=0; Fy=0 
 
 
 
 
 
 
But we need to use ‘equilibrium of a rigid body’ to determine t...

TYPICAL APPLICATION 
In crane lifting operations, the forces in the wires and chains that hold up the load have to be calculated to determine if they are strong enough and in the right position to stabilize the load. In this application the forc...

SIMPLE TRUSSES, THE METHOD OF JOINTS, & ZERO-FORCE MEMBERS 
Today’s Objectives: 
You will be able to: 
a)	Define a simple truss. 
b)	Determine the forces in members of a simple 
truss. 
c)	Identify zero-force members in a simple truss. 
 
 
 
APPLICATIONS 
 
Trusses are commonly used to support 
roofs. 
 
For a given truss geometry and load, how can you determine the forces in the truss members and thus be...

Long trusses are often used to construct large cranes and 
electrical transmission towers. 
 
The method of joints requires that many joints be analyzed before we can 
determine the forces in the middle of a large truss. 
 
So another method to determine those forces would be helpful.
