1. forces of 4N and 6N act at a point. By drawing suitable force diagrams find max and min resultant force and resultant force if the 2 forces axt as 50deg to each other.
2. the resultant of 2 forces, 4N and y N is a force of 8N. If the direction of the y force is reversed. The resultant is 3squareroot2N What's the value of y? (y=5)
doesn't sound urgent.
1. max is if both act in same direction. min if opposite direction. Go figure.
2. Too complicated to explain with no drawing... wait for someone else...
Question 2
Draw out, and use the power of trigo to solve
Might need to use simultaneous equations... at least that is what I think off-hand... a bit busy to answer your question fully now...
