Rocker arms contain the cams to give motion to the values timing.

But in some engine the cam is directly operate the valve. There is no rocker arm. A seem is placed between valve stem and cam.

This seem is calibrated.

But most of the engine the power from camshaft is transmitted through camshaft pulley belt drives to valves.

Power from main engine shaft is taken by the cam during running conditions. And the cam will transfer this power to the rocker arm because of its point contact. And finally this power will transfer to valve through its stem.

Camshaft helps the the valves to inlet and outlet of combusted air, some may possess pulleys drives and some may possess directly through chain.

In pushrod engine, rocker arm transmits power to the valve. But in some of the engines (OHC, DOHC) camshaft directly transmits power to the valves.

What is calibrated which engine use in calibrated?

What is the revolution of camshaft while crankshaft revolve on time?

The main role of cam shaft is to transmit the power push rods-rocker arm-engine valves. The cam shaft powered by crankshaft by means of gears.

Now a day all engines valves are operated by cam shaft directly with out any push rods and rocker arms.

Nowadays, valves are directly controlled by cam shaft. Rocker arm also needs a push rod to control the valves. That why we don't go for the rocker arm.
