An Internal combustion engine has a connecting rod of mass 2 kg and the distance between the centre of crank and centre of gudgeon pin is 25 cm. The Center of Gravity lies at a point 10 cm from the gudgeon pin along the line of centres. The radius of gyration of this system about an axis through the Center of Gravity perpendicular to the plane of rotation is 11 cm. If two masses are used instead of the connecting rod, one at the gudgeon pin and other at the crank pin. What will be the new radius of gyration?

The correct option is (d) N010 G02 X5 Y5 X10 Y10 R5

The best I can explain: Tool-Radius Compensation

Left hand G41

Right hand G42

Cancel tool-radius compensation G40

Tool-Height Compensation

Positive G43

Negative G44

Cancel tool-height compensation G49

Tool-radius compensations make it possible to program directly from the drawing, and thus eliminate the tool-offset calculation

G41 (G42) Dxx

Dxx: the radius of tool to compensate is saved in a memory unit that is named Dxx

G41/G42 is directly related with direction of tool movement and which side of part is cut.
