15. B as shown in the figure, if the magnitude of the three common point forces is F1 = 5N, F2 = 10N, F3 = 15N and θ = 37 ° respectively, the resultant force FX in the X direction=_______ N. On the Y side
Answer: 18; 6;
The resultant force of three common forces, 14N, 10N and 3N, may be?
A.0 B.3N C.10N D.40N
Could it be 27N
1 to 27N
1=14-10-3
27=14+10+3
If the angle between the two forces F1 and F2 does not change and the magnitude of F1 does not change, as long as F2 increases, the resultant force F will inevitably increase. Is that right?
Obviously wrong, for example, if the two left and right forces, F1 = 20n, F2 = 15N, F2 increase, the resultant force will gradually decrease and then increase
