1 PLASTIC DYNAMICS TROLLEYS A pair of carts, made from a single piece of moulded unbreakable ABS. These carts are rigid and strong enough to withstand routine rough usage or falls from workbench etc. 3 low friction wheels providing straight motion over long distances. A lockable spring- loaded exploder plunger has 2 levels of spring compression and is activated by a trigger on top of the trolley. A cushioned surface mounted on top of each cart enables placing of additional masses for increasing the effective weight of the cart. The carts can be stacked on top of each other to double or triple the overall mass. Velcro at the back end of each cart enables the study of inelastic collisions. Dimensions: 350 x 80 x 44mm. Cat No. Description Price Per FMD-050-100 Dynamics Trolleys - Plastic 51.35 pr 2 WOODEN DYNAMICS TROLLEYS A pair of trolleys fitted with ball bearing wheels to minimize friction. A spring loaded exploder plunger with 2 levels of spring compression is activated by a trigger on top of the trolley. A tough laminated surface mounted on each trolley allows the placing of additional masses for increasing the effective weight of the trolley. Velcro at the back end of each trolley enables the study of inelastic collisions. Dimensions: 350 x 80 x 44mm. Cat No. Description Price Per FMD-100-100 Dynamics Trolleys - Wooden 48.93 pr 3 LASCELLS HARDWOOD DYNAMICS TROLLEYS UNSPRUNG Traditional hardwood trolleys on three double row ball bearing wheels for exceptional free running. Wheels are set back from main body of the chassis, to reduce the chance of collision damage and a flat top is provided to allow the trolleys to be stacked in order to double mass. Cat No. Description Price Per FMF-455-100 Hardwood Dynamics Trolleys Unsprung 57.98 ea. 4 POWERED RACING CARS Three pull back and go wooden cars with rubber tyres for excellent grip. These cars can also free-wheel, which makes them suitable for a variety of dynamics experiments. Matchbox sized. Cat No. Description Price Per FMD-240-100 Powered Racing Cars 14.95 3 5 TICKER TAPE TIMER STANDARD Operates at a frequency of 50 to 60Hz, equivalent to that of the mains power supply, and is supplied with one roll of ticker tape and a pack of 100 Carbon Discs. It will give good results if operated from a 6-12V AC power supply. Higher voltage causes the tape to be subject to a greater drag. This device uses an electromagnet which activates a striker, producing dots via a carbon disk on the ticker tape. With 4mm terminal sockets. The Ticker Tape Timer is used in the measurement of velocity, acceleration and general timing. Cat No. Description Price Per FMD-250-100 Ticker Tape Timer, Standard 32.99 ea.
