The motion of a piston in an auto engine is simple harmonic. If the piston travels back and forth over a distance of 10 cm and t
chubhunter [2.5K]

Answer:

Maximum force will be 29040 N

Explanation:

We have given mass of the piston m = 1.5 kg

Amplitude A = 10 cm = 0.1 m

Angular speed \omega =4200rpm=\frac{2\times 3.14\times 4200}{60}=440rad/sec

We know that angular speed is given by \omega =\sqrt{\frac{k}{m}}

440=\sqrt{\frac{k}{1.5}}

Squaring both side

193600=\frac{k}{1.5}

k = 290400 N/m

Now force is given by F=kA=290400\times 0.1=29040N
