Laboratory

Sl Engineering Mechanics Lab. Workshop Practice
1 Verification of polygon law of force Carpentry shop Various jobs of wood like T-joint, Dovetail joint, Mortise & Tenon Joint, Square corner joint, Cross halving joint, electric switch board etc  using different types of hammer, chisel, steel rule, saw, bench vice, metal jackplane  etc.
2 Verification of parallelogram law of force
3 Verification of triangular law of force Fitting Shop Various types of metallic jobs like surface finishing of a flat plate, making V-grove in a metal piece, making regular hexagonal and pentagonal shaped piece etc using file, hacksaw,  punching rod, bench vice, hammer etc.
4 Determination of centre of gravity of various shapes.
5

Determination of coefficient of friction of rough and smooth surface.

Welding shop Basically 2 types of welding are done. These are arc welding and gas welding. In  arc welding ac/dc rectifier is used and in gas 2 gas cylinders containing oxygen(O₂) and acetylene(C₂H₂) are used. Various types of metallic joints are done using welding technology like lap joint, but joint, T-joint, pipe joint, corner joint etc.
6 Determination of parallel forces in a simply supported beam.
7 Experiment on screw jack Machine Shop

Lathe Machine: Simple turning operation, taper turning, step turning, and threading, knurling operation are done taking cylindrical job.

Shaper Machine: Rectangular groove, V-grove, step making, corner cutting in a given metallic cubic block are done. The tool movement is horizontal.

Slotting Machine: single and multiple equidistance slots and keyways are made in a circular job like a gear or shaft. The tool movement is vertical.

Grinding Machine:  Sharpening  of cutting tools is done used in various machines and apparatus using rotating grinding wheels (rough and smooth)

Drilling Machine: Radial drilling machine is used for heavy work like making holes of size 25 mm -35mm in very thick block and job. Bench drilling machines are used to make small holes around 10mm diameter in lighter and thin metal plate.

Milling Machine: It is highly precise and almost all metallic operation can be done here by engaging different tools as the requirement. Skilled person is highly desirable.
