Strength of Materials Lab Equipment: Complete List and Setup Guide

Strength of Materials Lab Equipment: Complete List, Experiments, and Setup Guide

The strength of materials laboratory (also called mechanics of solids or materials testing lab) is a core requirement for B.Tech and B.E. mechanical, civil, and manufacturing engineering programmes. This guide covers the complete strength of materials lab equipment list, experiment descriptions, AICTE/NBA/ABET compliance requirements, and procurement guidance for engineering colleges worldwide.

Complete Strength of Materials Lab Equipment List

1. Universal Testing Machine (UTM)

The UTM is the centrepiece of every materials testing laboratory. It applies tensile, compressive, and bending loads to test specimens and measures the resulting deformation.

• Capacity: 40 kN (for student labs), 100 kN, 200 kN (for research)
• Key experiments: Tensile test (stress-strain curve, Young’s modulus, UTS, elongation), compression test, bending test, shear test
• Scientico model: Universal Testing Machine Manufacturer India

2. Impact Testing Machine

Measures the energy absorbed by a material when struck by a sudden impact — assessing toughness and notch sensitivity. Supports Charpy (horizontal beam) and Izod (vertical cantilever) configurations.

• Capacity: 300 J (Charpy), 170 J (Izod)
• Key experiments: Charpy impact test; Izod impact test; comparison of brittle vs. ductile fracture energy
• Scientico model: Impact Testing Machine Manufacturer India

3. Torsion Testing Machine

Applies a twisting moment (torque) to a specimen and measures the angle of twist. Used to determine shear modulus (modulus of rigidity) and shear strength of materials.

• Capacity: 100 N·m to 1000 N·m
• Key experiments: Torsion test on mild steel and cast iron; determination of modulus of rigidity G; polar moment of inertia
• Scientico model: Torsion Testing Machine Manufacturer India

4. Hardness Testing Machine

Measures material resistance to surface indentation. The Universal Hardness Tester supports Brinell, Vickers, and Rockwell scales in a single machine.

• Brinell (HB): Ball indenter, 500–3000 kgf load — for soft metals and castings
• Vickers (HV): Diamond pyramid, 1–120 kgf — for thin materials and surface hardness
• Rockwell (HR): Diamond cone or ball, pre-load method — for rapid production testing

5. Spring Testing Machine

Applies compressive and tensile loads to helical springs to determine spring stiffness (spring rate), energy stored, and deflection characteristics.

• Key experiments: Load vs. deflection of close-coiled and open-coiled helical springs; determination of spring stiffness k
• Scientico model: Spring Testing Machine (available with hydraulic bench)

6. Deflection of Beam Apparatus

Applies central or off-centre point loads to simply supported and cantilever beams of different cross-sections (rectangular, I-section) to verify Euler-Bernoulli beam deflection theory.

• Key experiments: Load vs. deflection of simply supported beam; cantilever beam deflection; comparison of steel, aluminium, brass beams

7. Fatigue Testing Machine

Subjects a rotating-beam specimen to cyclic bending stress to determine the fatigue life and S-N (Wöhler) curve of materials — critical for machine design applications.

• Key experiments: S-N curve plotting; endurance limit determination; effect of stress concentration on fatigue life

8. Verification of Columns and Struts Apparatus

Demonstrates Euler’s buckling theory for slender columns under compressive loads with various end conditions (pin-pin, pin-fixed, fixed-fixed).

• Key experiments: Critical buckling load vs. effective length; verification of Euler’s formula Pcr = π²EI/(Le)²
