Question

an electric motor weighing 50 kg is mounted on 4 springs each of which has a spring constant of 2× 10^3 n/m^2 the motor moves only in vertical direction find the natural frequency of the system​

Answer 1

Explanation:

please mark me as a brainliest answer.

Answer 2

Answer:

The springs are in parallel. So equivalent spring constant = 4×4000Nm−1

Here, M=40kg

∴ Period of oscillation,

T=2π4016000−−−−−−√=2π20=π10=0.314s
