Engineering Mechanics If ‘P’ is the force acting on the body, ‘m’ is the mass of the body and ‘a’ is the acceleration of the body, then according to Newton's second law of motion, P - m.a = 0 P + m.a = 0 P/m.a = 0 P × m.a = 0 P - m.a = 0 P + m.a = 0 P/m.a = 0 P × m.a = 0 ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics If a number of forces are acting at a point, their resultant will be inclined at an angle 'θ' with the horizontal, such that tanθ = ΣH/ΣV tanθ = ΣV/ΣH tanθ = √(ΣV + ΣH) tanθ = ΣV × ΣH tanθ = ΣH/ΣV tanθ = ΣV/ΣH tanθ = √(ΣV + ΣH) tanθ = ΣV × ΣH ANSWER DOWNLOAD EXAMIANS APP
