Physics Laboratory Equipment (Applied Mech)
Inclined Plane
The instrument has been designed to study concepts of motion on an inclined surface and its relationship to the friction. All metal construction provides sturdiness and durability to this apparatus. It comprises two metal boards, hinged at one end. One side of inclined board has a linear scale graduated at every 5cm to measure linear distance along its length and it can be inclined and fixed at any angle from 0-40º to the horizontal measured on the attached angle measurer. A vertical scale 0-25cm is also printed on the angular scale to measure the height of inclined surface at any point. The end of the inclined board features an adjustable pulley wheel from which masses, weight pan etc. can be suspended. A plastic trolley with hook and a pan with lightweight cord are also provided with the inclined plane. Size of inclined surface 80mm. Supplied without masses.

Inertia Apparatus
A simple device to demonstrate the concept of inertia of a body at rest. Polished wooden stand has a receptacle at the top to contain a wooden ball along with a spring sheet metal striker mounted vertically on base. Also included are a wooden ball and a square piece of sheet metal. Pulling back the striker to different positions and releasing makes the ball move with square metal piece or drop in the receptacle demonstrates the concept of inertia of the ball.

Intermediate Spectrometer
This is a robust instrument designed specifically for student use, which nevertheless is capable of very high performance. The main structure is of heavy cast metal, with bright plated fittings. The complete instrument is suppliedwithwooden case.
Scale: The 150mm diameter circle with protective plastic shield is fixed to the telescope movement and the table is attached to the double ended vernier, which reads to 1 minute of arc. Both telescope and table rotation fine adjustment screws, and release of a clamping screw enables adjustment of both movements to bemade by hand.
Collimator: Mounted on fixed and fitted with 178mm focus achromatic objectives, 25mm clear aperture. Also fitted is a unilaterally adjustable slit7mmlong.
Telescope: Mounted on moveable pillar and fitted with 178mm Focus achromatic objective, 25mm clear aperture. Also fitted is a 8× Ramsden eyepiece and a glass cross line graticule. Both the telescope and collimator have rack and pinion focusing. Means are provided for leveling the axis of both optical units and for squaring them to axis ofrotation.
Prism Table: The table is marked with lines to assist placing the prism with respect to the table leveling screws.
Standard Accessories Supplied: 1 Prism clamp, 1 diffraction grating holder, 1 magnifier, 1 tommy bar for adjusting optical axis, 1 wooden case.

Lamp Holders
A variety of ‘MES’ and ‘SBC’ lamp holders some batten mountable for use in the science laboratory.
(Wikipedia excerpt:…A lightbulb socket, lightbulb holder, light socket, lamp socket or lamp holder is a device which mechanically supports and provides electrical connections for a compatible electric lamp.[1] Sockets allow lamps to be safely and conveniently replaced (re-lamping). There are many different standards for lamp holders, including early de facto standards and later standards created by various standards bodies. Many of the later standards conform to a general coding system in which a socket type is designated by a letter or abbreviation followed by a number.
The most common type of sockets for mains electricity are Edison screws, used in continental Europe and North America, while bayonet mounts dominate in the Commonwealth countries, except Canada, and in the automotive industry. Fluorescent lamps typically require a two-pin, unthreaded socket. Not all lamps require a socket. For example, some miniature lamps have wire leads suitable for direct connection to screw terminals or other wires, and some reflector lamps provide screw terminals for electrical connections…..” ).

Lenz Law
Arco Lenz Law apparatus is a simple and effective way to demonstrate induction & Lenz Law of electrodynamics. The metal hoops (one open and one closed) are freely moving on a centrally mounted pin. In the product photo above, you have a complete closed circuit (loop) on the right. When a magnetic field is introduced (from a bar magnet being moved toward the closed loop), we have an electrical current and a magnetic field that will repel against the original magnetic field. This is demonstrated when the closed loop moves away from an approaching bar magnet. This is Lenz law. Alternately, when you approach the open circuit (open loop) on the left with a bar magnet, nothing will happen.
