PLTW Principles of Engineering Activities

A series of questions and answers where you have to describe the motion of a pulley, including: - which direction the pulleys in a system are rotating in (clockwise or counterclockwise) based on a information given about the input pulley, - what the ratio is between the input pulley and the other...

Calculating gear ratios, as well as unanswered questions about pulley drives and sprockets.

The questions and answers investigate an energy conversion system designed to change electrical energy into mechanical energy. It includes problems on: winch data; measures like force, distance, work, and power; and calculations of efficiency to compare energy input versus energy output.

A walkthrough of the procedures and results of an experiment that our class did in order to learn about designing a motor to produce the maximum power output, using a DC power supply and a multimeter (among other equipment to construct the motor).

Questions about thermodynamics, taken on 13 December 2019. I got a 100% on this quiz.

Researching insulation.

An experiment where we calculate weight of a person based on the deflection of a beam. Includes calculations of the modulus of elasticity and uses pre-loading and applied load distances.

This assignment consists of practice problems creating free body diagrams (FBD) to evaluate all of the forces interacting with those objects.

Drawing free body diagrams to help calculate the magnitude and direction of forces.
