Question 1: Basic Physics A force of 50 N is applied to move a box at a constant speed over a horizontal surface. What is the frictional force acting on the box? Options: - a) 0 N - b) 25 N - c) 50 N - d) Cannot be determined Answer: c) 50 N Since the box moves at a constant speed, according to Newton's first law, the net force on the object is zero. This means the applied force equals the frictional force opposing the movement. Therefore, the frictional force is 50 N. Question 2: Gear Systems In a gear train, gear A (driver gear) has 20 teeth, and gear B (driven gear) has 40 teeth. If gear A turns clockwise at 120 rpm, what is the rotational speed and direction of gear B? Options: - a) 60 rpm, clockwise - b) 60 rpm, counterclockwise - c) 240 rpm, clockwise - d) 240 rpm, counterclockwise Answer: b) 60 rpm, counterclockwise The gear ratio is determined by the number of teeth: Gear ratio = Number of teeth on gear B / Number of teeth on gear A = 40 / 20 = 2 Since gear A is the driver gear with 120 rpm: Speed of gear B = 120 rpm / 2 = 60 rpm Direction: Gears in mesh rotate in opposite directions, so gear B rotates counterclockwise. Question 3: Levers A lever is balanced when a load of 200 N is placed 3 meters from the fulcrum. How far from the fulcrum should the effort be applied to balance a load of 300 N? Options: - a) 2 meters - b) 3 meters - c) 4.5 meters - d) 1.5 meters Answer: c) 4.5 meters 3 For a lever to be balanced: Effort × Effort arm = Load × Load arm Let effort distance = d Effort × d = 300 N × 3 m Effort × d = 900 Nm Given effort = 200 N: 200 N × d = 900 Nm d = 900 Nm / 200 N = 4.5 m Therefore, the effort must be applied 4.5 meters from the fulcrum. Question 4: Fluid Mechanics What is the pressure exerted by a column of water 10 meters high? (Density of water = 1000 kg/m³, acceleration due to gravity = 9.8 m/s²) Options: - a) 98,000 Pa - b) 9,800 Pa - c) 1,000 Pa - d) 10,000 Pa Answer: a) 98,000 Pa Pressure due to a fluid column is given by: P = ρgh Where: ρ = density = 1000 kg/m³ g = acceleration due to gravity = 9.8 m/s² h = height = 10 m Calculating: P = 1000 × 9.8 × 10 = 98,000 Pa Question 5: Thermodynamics A machine consumes 500 J of energy to lift a load. If the efficiency of the machine is 80%, what is the useful work done? Options: - a) 400 J - b) 500 J - c) 625 J - d) 800 J Answer: a) 400 J Efficiency (η) = Useful work / Input energy Rearranged: Useful work = η × Input energy = 0.80 × 500 J = 400 J --- Tips for Preparing for Mechanical Aptitude Tests Preparing effectively can make a significant difference in your test performance.
