) and identifying the three types (1st, 2nd, and 3rd degree). Transmission Mechanisms: Pulleys (Poleas):

3. Materials

• Q: The ability of a material to withstand impact without fracturing is:
  A: Toughness.
• Q: Heat treatment that softens steel for machining:
  A: Annealing.
• Q: Stress = Force / Area – units:
  A: Pa (N/m²) or MPa.

Mechanical Advantage: The test often asks for the specific formulas used to calculate force reduction when adding pulleys to a hoist system.

Study of first, second, and third-class levers and the law of the lever. Poleas y Polipastos (Pulleys and Hoists):

Polipastos: Cuantas más poleas móviles tenga el sistema, menor será el esfuerzo necesario para elevar una carga.
