Demonstrate how to string length and mass affect the movement of a pendulum. Simply attach strings of different lengths with different weights to the pendulum clamp and observe the differences in motion. Includes a heavy-duty pendulum clamp, a support stand with a 6 in. x 11 in. support base, and a 36 in. L rod, four 25 mm pendulum bobs…
Mirrors are great for numerous applications. They demonstrate reflection and refraction simply and effectively. They are an easy way to teach the principles of optics. Made of Plexiglass, which is much stronger than glass (will break/crack, but will not shatter like glass.)
For use with ripple tank, to operate both the ripple motor and the illuminate. Output 12 V A.C. max 24 W for illuminate and 0 to 6 V D.C. variable for ripple motor. Operates from 240 V A.C. mains.
Students can quantitatively see how pressure on an object changes as it moves deeper under a fluid with this interactive density pressure manometer activity. A hollow drum covered with a rubber membrane is connected to an open-end manometer. When the drum is pushed under water the pressure on the rubber membrane increases the pressure inside the tubing, causing the manometer…
Strong, all-metal construction. Height can be adjusted vertically and tightened at any point from parallel with the clamping surface up to 2 in. above it. Mount on a surface up to 2 in. thick. The aluminum pulley is 1-1/8 in. dia.
The Pulley Demonstration Set is designed to illustrate the working principle of simple machines. From the wheels on a bicycle to the gears in a car, the Pulley Demonstration System helps explain how things work. It helps students to understand the concepts of mechanical advantage, the efficiency of fixed and moveable pulleys, etc. Students perform quantitative experiments on fixed and…
Aluminum pulley, 70 mm diameter in a metal bracket with two clamping screws for bench and rod support respectively. The bracket may be clamped to a board or bench edge up to 38 mm thick, screwed to a flat surface or held in a 13 mm diameter support rod.
Brightly colored single and double tandem pulleys will add fun to your experiments. Made of durable lightweight plastic these 50mm diameter pulley blocks are held in a chrome plated metal frame. Illustrated activity guide included. Ages 7+.
Sturdy nylon constructed clamp pulley. The ball bearing sheave is 4.5 cm in diameter and can be adjusted from flush with the tabletop to 13 cm above it. In addition, the pulley can be rotated 360° to suit any experimental setup. Attached to tables up to 4.5 cm thick.
A low cost pulley for simple machines experiments, rigid plastic sheave with a deep V – groove, 50 mm in diameter. Can be attached to surfaces up to 25 mm thick.
To provide a simple means of producing single or multiple rays of light for use in elementary optics. Made of die-cast alloy, the ray box has an open front and vertical internal grooves to accommodate a slit plate and a cylindrical lens. Supplied complete with a plastic plate having single and triple slits, a 12 V 24 W SBC line…
