I.T.I.E.C.E. - Industrial Training Institute Entrance Competitive Examination
I.T.I.E.C.E. (Industrial Training Institute Entrance Competitive Examination) governs admission to ITI trades such as Electrician, Fitter, Welder, Turner and Mechanic. It tests mathematics, science, general knowledge and reasoning.
Core rules
- Mathematics: arithmetic, algebra, geometry, mensuration and trigonometry.
- Science: basic physics and chemistry, units, materials and safety.
- Trade awareness: common tools, measuring instruments and workshop practice.
- Reasoning: series, analogy, classification and spatial reasoning.
- For the electrician trade, distinguish conductor, semiconductor and insulator; for fitter trade, distinguish try square from bevel protractor.
Worked example
A simple machine lifts a load of 500 N with an effort of 100 N. Its velocity ratio is 6. Find the mechanical advantage and efficiency. Reasoning: MA = load/effort = 500/100 = 5. Efficiency = (MA/VR) × 100 = (5/6) × 100 = 83.3%. A machine cannot have efficiency above 100%; if you get that, MA and VR have been swapped.
Traps
- Confusing mechanical advantage with velocity ratio.
- Using the wrong unit for force or work.
- Choosing a tool by shape without checking its stated function.
- Ignoring safety instructions embedded in the stem.
- Assuming an ideal machine when friction is mentioned.
