Sanchay put a 1 cm stick of gum through a `(1xx3^(-2))` machine. How long was the stick when it came out?

Stretching Machine Suppose you have a stretching machine which could stretch almost anything. For example if you put a 5 metre stick into a (xx4) stretching machine (as shown below), you get a 20 metre stick. Now if you put 10 cm carrot into a (xx4) machine, how long will itbe when it comes out?

A uniform wooden stick of mass 1.6 kg and length l rests in an inclined mannar on a smooth, vertical wall of height h(ltl) such that a small portion of the stick extends beyond the wall. The reaction force of th wall on the stick is perpendicular to the stick. The stick makes an angle of 30^@ with the wall and the bottom of the stick is on a rough floor. The reaction of the wall on the stick is equal in magnitude to the reaction of the floor on the stick. The ratio h/l and the friectional force f at the bottom of the stick are (g = 10 ms^2)

Two pistons of a hydraulic machine have diameters of 30.0 cm and 2.5 cm. What is the force exerted on the larger pistion when 40 kg wt. is placed on the smaller piston? If the smaller pistion moves in through 6 cm, how much does the other pistion move out ?

A skirt that is 35(7)/(8)cm long has a hem of 3(1)/(8)cm. How long will the skirt be if the hem is let down?

Shrinking Machine In a shrinking machine, a piece of stick is compressed to reduce its length. If 9 cm long sandwich is put into the shrinking machine below, how many cm long will it be when it emerges?

A metre stick is balanced on a knife edge at its centre. When two coins, each of mass 6 g put one on top of the other at the 12.0 cm mark, the stick is found to be balanced at 45.0 cm. What is the mass of the metre stick?
