The Discover Engineering kit is the perfect tool for introducing students to engineering concepts with engaging hands-on activities. With exciting cutting-edge curriculum, every student can develop new skills as they build confidence, explore various disciplines, and improve problem solving abilities. These projects teach students about topics including gear trains, power ratios, and complex machines while they build trebuchets, cart launchers, transmission models, and more!
Discover Engineering now features the new 3-dimensional interactive curriculum, the 3DIC. Step by step instructions, video playback, and the ability to highlight individual pieces in builds helps students work through engineering projects quickly and with confidence. Each Discover Engineering Kit comes with 2 licenses for the complete 3DIC-Discover Engineering (3DIC-DE).
Science: A worm gear motion is not reversible. A worm can drive a gear to reduce speed but a gear cannot drive a worm to increase it. As the speed is reduced the power to the drive increases correspondingly. Worm gears are a compact, efficient means of substantially decreasing speed and increasing power. Ideal for use with small electric motors.
Technology: The use of the worm gear with guitar strings and crescent wrenches - enabling the devices to lock. Breaks for conveyor systems. Many worm gears have an interesting property that no other gear set has: the worm can easily turn the gear, but the gear cannot turn the worm. This is because the angle on the worm is so shallow that when the gear tries to spin it, the friction between the gear and the worm holds the worm in place.
Engineering: Simple Machines: ScrewA screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. It is one of the six classical simple machines.
Math: Gear ratiosA worm can be used to reduce speed. For each complete turn of the worm shaft, the gear shaft advances only one tooth of the gear. In this case, with a twelve tooth gear, the speed is reduced by a factor of 12. Also, the axis of rotation is turned by 90 degrees.
