A simplified turning moment diagram of a four-stroke engine is shown in the given Fig.80. If the mean torque ' \(T_{m}\) ' is \(10 \mathrm{Nm}\), the estimated peak torque ' \(T_{p}\) ' will be (assuming negative torque demand is negligible)

(a) \(80 \mathrm{Nm}\)

(b) \(120 \mathrm{Nm}\)

(c) \(60 \mathrm{Nm}\)

(d) \(40 \mathrm{Nm}\).
