A single cylinder, four-stroke I.C. engine rotating at \(900 \mathrm{rpm}\) has a crank length of \(50 \mathrm{~mm}\) and a connecting rod length of \(200 \mathrm{~mm}\). If the effective reciprocating mass of the engine is \(1.2 \mathrm{~kg}\), what is the approximate magnitude of the maximum 'shaking force' created by the engine?

(a) \(533 \mathrm{~N}\)

(b) \(666 \mathrm{~N}\)

(c) \(133 \mathrm{~N}\)

(d) None of the above.
