ME2256 STRENGTH OF MATERIALS LAB 0 0 3 2
(Common to Auto, Mechanical & Production)
OBJECTIVE
To supplement the theoretical knowledge gained in Mechanics of Solids with practical
testing for determining the strength of materials under externally applied loads. This
would enable the student to have a clear understanding of the design for strength and
stiffness
LIST OF EXPERIMENTS
1. Tension test on a mild steel rod
2. Double shear test on Mild steel and Aluminium rods
3. Torsion test on mild steel rod
4. Impact test on metal specimen
5. Hardness test on metals - Brinnell and Rockwell Hardness Number
6. Deflection test on beams
7. Compression test on helical springs
8. Strain Measurement using Rosette strain gauge
9. Effect of hardening- Improvement in hardness and impact resistance of steels.
10. Tempering- Improvement Mechanical properties Comparison
(i) Unhardened specimen
(ii) Quenched Specimen and
(iii) Quenched and tempered specimen.
11. Microscopic Examination of
Hardened samples and
(ii) Hardened and tempered samples.

ME 2257 COMPUTER AIDED MACHINE DRAWING LABORATORY
0 0 4 2
OBJECTIVE
i) To make the students understand and interpret drawings of machine
components so as to prepare assembly drawings either manually and using
standard CAD packages.
ii) To familiarize the students with Indian Standards on drawing practices and
standard components.
DRAWING STANDARDS
Code of practice for Engineering Drawing, BIS specifications – Welding symbols, riveted
joints, keys, fasteners – Reference to hand book for the selection of standard
components like bolts, nuts, screws, keys etc.
2-D DRAWINGS
Limits, Fits – Tolerancing of individual dimensions- Specification of Fits- Manual
Preparation of production drawings and reading of part and assembly drawings.
CAD PRACTICE (USING APPLICATION PACKAGES)
Drawing, Editing, Dimensioning, Plotting Commands, Layering Concepts, Hatching,
Detailing, Assembly, basic principles of GD&T (geometric dimensioning & tolerancing)
ASSEMBLY DRAWING (MANUAL & USING APPLICATION PACKAGES)
Manual parts drawing and preparation of assembled views given part details for
components followed by practicing the same using CAD packages.
Suggested Assemblies:
Shaft couplings – Plummer block – Screw jack- Lathe Tailstock – Universal Joint –
Machine Vice – Stuffing box- safety Valves - Non-return valves- Connecting rod -Piston
and crank shaft- Multi plate clutch- Preparation of Bill of materials and tolerance data
sheet Total Number of Periods: L=15 P= 45 60
Use of standard CAD application packages is recommended from the point of view of
requirement by industries. However to encourage our national efforts in indigenous
development of software packages with focus on open source, students may be
encouraged to work with “CollabCAD Software”, developed by:
National Informatics Centre (CAD Group), Govt. of India, A-Block,
C.G.O. Complex, Lodhi Road, New Delhi 110003, 2003”
