🎯 Exam Strategy

Guaranteed Marks Plan

How to approach each part of the Physics Mechanics exam for maximum marks.

Part A
20 MCQs × 1 = 20 marks
Target: 17–20 / 20
  • Resultant of forces & Lami's theorem 4/4
  • Centroid formulae (semicircle, triangle) 4/4
  • MOI — $bd^3/12$ vs $bd^3/3$ 4/4
  • SUVAT kinematic equations 4/4
  • Projectile motion (range at 45°) 4/4
  • Friction — μs, μk, angle of friction 4/4
  • Coefficient of restitution e values 3/4
  • Mass MOI formulae (disc, rod, sphere) 3/4
  • τ = Iα (rotational Newton's law) 3/4
  • Work-energy theorem applications 3/4
Part B
5 Questions × 10 = 50 marks
Target: 40–50 / 50
QUnitExpected Topic
21U1FBD + Equilibrium of a rigid body or Lami's theorem 🔥
22U2Friction on inclined plane OR Truss by Method of Joints 🔥
23U3Centroid of composite area with cutout (T, I, or L section) 🔥
24U3/U4MOI using Parallel Axis Theorem OR Projectile/Dynamics 🔥
25U4/U5Work-Energy theorem OR Angular Kinematics / Torque
Exam Writing Tips
General Advice
Score Maximisation
💡 FBD Rule: Always draw a clear, labelled Free Body Diagram before writing any equilibrium equation. Even a partial FBD earns marks.
💡 Centroid Tabulation: For centroid/MOI questions, always present your work in a table format: Shape | Area | x̄ | ȳ | Ax̄ | Aȳ. This guarantees method marks.
💡 Units: Always write units at every step — N, m, N·m, m⁴, rad/s². Missing units = mark deduction.
💡 Sign Convention: State your sign convention at the start (Clockwise +ve or CCW +ve). Stick to it throughout. Inconsistency loses marks.
