Material: Nickel plated brass.
Pin, safety, medium size, for securing wraps and bandages.
Length: medium size, 40mm.
Function ofthrust block with cup springs:
The rack isconstantly pressed against the pinion, therefore no backlash.
Possible Demonstrations:
Steering gearratio
Movementcycle of steering gear.
The apparatus shows precisely how Castor Camber King Pin Inclination are set up and how centre point steering is achieved. A wheel and means of altering the offset are included so that everything affecting centre point steering can be varied.
A hand driven rotating turntable simulates a rolling road, and may be turned at a slow enough speed to study wheel stability under running conditions.
Students often experience difficulty in understanding the principles of front wheel set-up on road vehicles, since the geometry involves angles in three dimensions. Vernier scales measure the Castor Angles And King Pin Inclination, while toe in and camber angles are measured from a longitudinal and vertical datum in the way in which they would be determined on a real vehicle.
Experimental Capabilities:
To demonstrate the effect of wheel offset
To observe the dynamic stability of the wheel under running conditions
To show how castor, camber and king pin inclination are set up
To show how the steering linkage is related to toe-in.
The practice kit provides the material necessary for students to systematically learn how components can be joined together in a professional way using pins. Both flat and cylindrical parts are pinned together. We recommend that the exercises are carried out in a workshop, as all preparations such as scribing, drilling, clamping, reaming and joining must be carried out in a correct and proper manner by the student. The material is clearly laid out on a plastic tray. The well-structured instructional material outlines all the necessary technical information and provides a step-by-step guide through the exercises.

A heated flat plate with surface thermo couple may be directly compared with a similar pinned plate and finned plate also fitted with a surface thermo couple.
A bench top accessory designed to allow students to experimentally investigate both free (natural) convection and forced convection. Three plates with integral heaters and temperature sensors are also supplied that are designed to fit in the central aperture in the wind tunnel. The accessory includes a small, variable velocity wind tunnel with a digital velocity meter and a central aperture.
This supplement to the universal material tester enables deep-drawing and cupping experiments to be performed to assess the material properties of thin sheet. A mirror permits the underside of the specimen to be observed and thus makes it possible to see exactly how cracking starts. The deep-drawing conditions are similar to those used in practice. A sheet specimen is clamped between the die and the holder. The specimen is then deformed using a spherical punch until it cracks. Using these device thin sheets up to thickness of 2mm can be investigated.

The PBM DP arrangement 3 Roll Pyramid Type Hydro-MechanicalPlate Bending are planned with twofold side pre-squeezing course of action. The top roller is settled and pre-pinching by bothbase rolls are through pressure driven barrels. The job is bolstered from oneend to complete pre-squeezing and whole shell is moved to wanted curve span. This component makes the machine more gainful and reasonable for taking care of overwhelming employments. Flip side pre-squeezing is done by second base move to finish the shell. Theone of a kind outline allows the pre-squeezing of employment by both baserolls; subsequently the occupation is finished in single operation. Thecomplete shell is set up in single operation.
Features:
3 Roll PYRAMID Type outline with twofold pre-squeezing gameplan
Twisting rolls are made of combination steel.
Dropper end assurance by pressure driven barrels.

Two base rolls are force driven via planetary apparatus boxwith electric or water powered engine.
Low part, smooth operation and less power utilizationbecause of water powered framework works at lower weight in littler thickness.
Top roll is repaired and base moves and down.
Base moves up-down through water powered chambers.
The Pin Jointed Frameworks Apparatus mount onto two end supports. One support has a pivoting arrangement whilst the other has pivoting and rolling arrangement. Each framework member has a strain gauge arrangement attached. The signal from the loading mechanism and strain gauges is fed directly into the Interface. The loads on the Pin Jointed Frameworks Apparatus are applied at known joints by using the screwjack loading mechanism supplied.
The Pin Jointed Frameworks Apparatus enables students to assemble two Pin-Jointed Frameworks (warren and basic roof truss) to measure the strains (hence stresses) and joint deflections. Each member of the framework can be easily interconnected with each other by use of simple joints that are designed to create a truly pin joint.
