Question

if the forces are in ratio 5:2 then find the minimum and maximum of their resultant ratio

Answer 1

Let the common multiple be x. So, the forces are 5x & 2x.

Maximum resultant is (a+b) &
Minimum resultant is (a-b).

So, maximum resultant force= a+b = 5x+2x = 7x
minimum resultant force = a-b = 5x-2x = 3x
