Question

Two snowmobiles are pulling a third snowmobile each exerting a force of 3 kN at the attached point at A. The maximum combined force that the two cables can exert on the attachment to the third snowmobile in any direction is 5 kN. Assume 0 less than equal tp alpha less than equal to 90°.
Determine the range of alpha before the 5 kN is exceeded

a)by means of a graphic solution and
b) using trigonometry (sine and/or cosine rule)

Answer 1

From the image5N-3cos3c Hence the angle α:: 67.110 5N-The force acting on the third snow mobile is only the x component of force, The y component of force will get cancelled. Hence the angle 5N o 67.11°
