For a slider-crank mechanism with radius of crank r, length of connecting rod l, obliquity ratio n, crank rotating at an angular velocity θ; for any angle θ of the crank, match List I (Kinematic Variable) with List II (Equation) and select the correct answer :
List I
A. Velocity of piston
B. Acceleration of piston
C. Angular velocity of connecting rod
D. Angular acceleration of connecting rodList II
1. ω/n cosθ
2. ω2r[cosθ + (cos2θ)/n]
3. -ω2/n sinθ
4. ωr[sinθ + (sin2θ)/n]
b. A→2, B→4, C→3, D→1
c. A→4, B→2, C→1, D→3
d. A→2, B→4, C→1, D→3
