Question

o is the centre of a regular hexagon abcdef. forces of 1, 2, 3,4,5and 6kg. wt. act along oa , ob, OC, od, oe, and of respectively. find the magnitude of the resultant and angle which its line of action makes with OC


​

Answer 1

Answer:

Fnet=6 kgwt and it makes an angle of 120° clockwise with oc.

Step-by-step explanation:

The three forces, i.e. 1,2,3 kgwts act in opposite directions of 4,5,6 respectively.

So we can cancel the smaller forces and write three forces, all of them of same magnitude(3kgwt) along of, oe and od.

Now the resultant of these three forces will act along oe.

Magnitude of resultant:

{3+3cos(60°) +3cos(60°) }kgwt= 6 kgwt
