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...

Solids and Structures 1 (ENGG110) 2023 Frictional Forces Draw FBD of block at rest on inclined surface Pause the video and try this! FBD of block • W is weight of block = Mg due to gravity acting through G centre of mass • N is normal reaction between block and surface • F is frictional force opposing motion What is friction? Max friction Min friction

Solids and Structures 1 (ENGG110) 2023 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...

Solids and Structures 1 (ENGG110) Equilibrium of a particle (at a point) Outline • Co-planar (2-D) equilibrium of forces • FBDs • Concept quiz • Support reactions in 2-D • Quick summary Hook 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...

Solids and Structures 1 (ENGG110) 2023 1-Pin-jointed Frames 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.

Chapter 01: Introduction to Dental Materials MULTIPLE CHOICE 1. Until 1970, which of the following groups of dental auxiliaries were allowed to perform intraoral functions in all states? 1. Dental hygienists 2. Registered dental assistants 3. Certified dental assistants 4. On-the-job trained dental assistants a. 1, 2, 3, 4 b. 1, 2, 3 c. 1, 2 d. 1 ANS: D Until 1970, only the dental hygienist was allowed to perform intraoral functions in all states. Although laws vary ...
