AI Thread Summary
To solve for the resultant of the three forces acting on an object, one must first break down the forces into their vector components. The 30N and 45N forces act at a 120-degree angle to each other in the horizontal plane, while the 50N force acts perpendicular to this plane. The magnitude of the resultant can be calculated using vector addition, considering both the horizontal and vertical components. The friend's result of 96.8N and an angle of 51.7 degrees off the plane of the first two vectors suggests a correct approach, but verification through proper vector calculations is necessary. Understanding the 3D nature of the problem is crucial for accurate results.

3d Vectors Very Hard!

Three Forces of 30N , 45N and 50N act on an Object. The first act at an angle of 120 to each other the third is perpendiuclar to the plane of the first two. Find the Magnitude of the resultant, and the angle which the resultant makes with the plane containing the first two forces.

Any hints or help to help me start this question thanks!

Hmm... my friend got 96.8N, 51.7 degrees off of the plane of the 1st 2 vectors
is he correct, and how did he derive this answer?
 
anyone with anything i don't know where to solve the resultant... its a 3D with the 50N going upwards and 30 and 45N both Affecting at an 120 degree angle! Its Reall hard!

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
