A single fixed pulley lifts a 60 N crate. How much pulling force is needed (ignoring friction)?1 / 10

60 N. A fixed pulley has MA = 1, so the effort force always equals the load's weight — only the direction changes.

What is a gear?1 / 10

A gear is a wheel with teeth around its edge. The teeth are what make gears special — they let one gear grab onto another gear and turn it.

An engineer finds a wiring flaw in a product two days before it ships. Fixing it means missing the launch date. What's the ethically correct first move?1 / 8

Report the flaw and its safety implications to the appropriate people immediately — don't decide alone to stay silent to protect the launch date. The team may still find a fix in time, or may decide to delay; either way, the decision needs to be made with the safety information on the table, not hidden.

Why is a tower with a wide base more stable than one with a narrow base?1 / 8

A wide base spreads the tower's weight over more floor space, so it takes a much bigger push to tip it over. A narrow base balances on a tiny spot, so even a small push knocks it off balance.

What is the method of joints?1 / 10

A way to find the force in every member of a truss by isolating one joint (pin) at a time, treating it as a particle in static equilibrium, and writing ΣFx = 0 and ΣFy = 0 for the forces meeting there.
