A light rod ,12 cms long is suspended in a horizontal position by mean of two verticle strings. One string can stand a tension of 10gms and other of 20gms . a ring weighing 25gms can slide along the rod. find the least distance of the ring fromthe string .

Two likr paarallel forces P and Q act a given point of a body . If Q be changed to \(P^2\over{Q}\), show that the line of action of the resultant is the same as it would be if the forces were simply interchanged.

Two like parallel forces P and Q act at points A and B of a body .Their resultant meets AB in C .When the forces are interchanged , the resultant meet AB in D . if AC=DC , show that \(P:Q::2:1\)

The resultant of two like parallel forces P and Q passes through a point O .when P is incresed by R and Q by S , the resultant still passes through O and also when Q,R replaced P,Q respectively. show that

\(S={Q^2\over{P^2}}=R-{(Q-R)^2\over(P-Q)}.\)

Two unlike parallel forces P and Q (P>Q) act at A and B resp. if P and Q both increased by x show that the resultant will move through a distance \(xAB\over{P-Q}\)

P and Q are two like parallel forces . IF P be moves parallel to itself through a disance x, show that their resultant moves through a distance 

\(Px\over{P+Q}\)

P and Q are two parallel forces . Even on increasing them by x and y respec. the position of their resultant does not changed . prove that 

P:Q::x:y.

A light rod is acted upon by three parallel forces P,Q,R acting at a three point 4cm , 20cm, and 16cm repct. from one end . If the rod is in equalibrium , show that 

P:Q:R=1:3:4.
