ULTIMATE PULLEYS
Ultimate Pulleys is a new, exciting, and versatile equipment module that provides a complete lab for rotational dynamics, motion, and principles of machines. As a machine, four pulleys can be arranged with mechanical advantages of up to 4:1. As a dynamics experiment, students can easily measure angular speed, linear speed, and acceleration using photogates. The spinner (included) allows students to change the moment of inertia while keeping the total mass constant. A notch in the pulley allows students to attach a hanging mass to supply constant torque. Extension and compression springs provide the ability to conduct many experiments including Hooke's Law and mechanical oscillators.
Students can explore many additional concepts including Newton’s Laws, force, mass, acceleration, rotational inertia, torque, work, energy, simple machines, conservation of momentum, and mechanical advantage.
Ultimate Pulleys includes: 1 Hardwood Pulley Block, 4 Pulleys, 1 Compression Spring, 1 Extension Spring, Yellow String with Cord Locks, Red String, Weight Hanger, Mounting Hardware
