Forms of Energy, Weight, Work and Mechanical Stress
CSP written lesson, 8 min read. CSP Domain 6: Occupational Health and Applied Science
Written with AI help from the rules it covers, then fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.
What you'll learn
- Define potential and kinetic energy and calculate each in foot-pounds
- Explain why doubling speed quadruples kinetic energy
- Calculate work as force times distance and convert foot-pounds to joules
- Name and describe the five forms of mechanical stress
- Calculate tensile and shear stress as load divided by area and compare it with strength
What this lesson covers
This lesson covers the physics behind many struck-by, dropped-object and structural failures: potential and kinetic energy, work, the five forms of mechanical stress, and how stress compares with a material's strength. You will calculate the energy of a falling object and the tensile stress in a rod, and see why speed matters more than mass.
