Fletcher Trolley Engineering Lab Training Systems. Features Traditional design Self-contained Bench mounted Total mass of moving system can be maintained constant for different acceleration masses Five trolley masses Acceleration determination by ink trace Confirmation of Newton's Second Law of Motion Determination of Gravitational Acceleration Three year warranty Range of Experiments To show that a force causes a mass to accelerate, and that the acceleration is proportional to the force To compare experimental and theoretical values of forces required to accelerate a given mass To determine the acceleration due to gravity, g Description This type of equipment has been used for many years to introduce students to accelerated linear motion, in particular the dependence of the acceleration on the net force causing the motion. Confirmation of Newton's second law of motion and the determination of gravitational acceleration are possible. This strongly built traditional apparatus produces very accurate results. The trolley has five removable weights. During an experiment, the total mass of the moving equipment can be maintained constant by transferring weights from the rear of the trolley to the load hanger. Acceleration is measured using an inked brush attached to a vibrating arm. This traces out an oscillatory trace on a piece of paper fixed to the trolley.

For performing experiments on acceleration. Light metal track 1720 x 150 mm with levelling feet, felt covered stops at either ends. An aluminium pulley 50 mm diameter, clamp for vibrator and automatic pen release. Aluminium trolley 690 x 80 x 65mm with three wheels mounted on ball bearings, five holes to accommodate cylindrical masses each approx. 350gm. Vibrates 600mm long with clamping marks at 5 and 8 Hz and pen holder with one each wood blocks 150 x 75 x 13mm, 150 x75 x 50mm without pen and paper.
