Question

Q2. Three forces F1,F2 and F3 of magnitude 10 Newton ,15 Newton and 20
Newton acting along lines whose perpendicular distance from a given
turning point P are 5 m, 6 m and 2 m respectively .Arrange the magnitude
of moment of these forces about the given turning point and descending
order. *
O M1<M2<M3
M1>M2>M3
M2>M1>M3​

Answer 1

Answer:

F1 = 10N

F2 = 15N

F3 = 20N

Explanation:

distance of F1 from turning point P = 5m

,,, ,, F2,, ,,, ,,, ,, = 6m

,, ,, ,, F3 ,, ,, ,, ,, = 2m

moment of force (M1) F1 about turning point P = 10×5

M1 = 50N/m

similarly,

M2 = 15×6

M2 = 90N/m

& M3 = 20×2

M3 = 40N/m

so, M2>M1>M3 answer
