Aforce of 100 n is applied to the brake pedal, which acts on the cylinder—called the master—through a lever. a force of 500 n is exerted on the master cylinder. pressure created in the master cylinder is transmitted to four so-called slave cylinders. the master cylinder has a diameter of 0.55 cm, and each slave cylinder has a diameter of 2.50 cm. how much pressure is transmitted in the hydraulic system? express your answer in pascals and in atmospheres.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
