Im sorry for the late reply and i just want to say thank you for attempting to help me and i did get it done with the correct anwsers but the amount of confusion i was in and the help i needed this would have had over 200 replies before i got the anwser right but thanks for trying to help me i...
Im sorry i get what your trying to say but i just can't relate that to help me because in my mind this is how I am working it out Στ=τ(folcum) + -τ(rectangle) and the rectangle is mg and i know the net force is 0 but i don't get what you are trying to say ? I am sorry for being so helpless i...
Okay so we have the MG from the rectangle and we have Fa from the fulcrum and the length is 20 cm but the radius from the rectangle is 11 cm and I know you have to solve for mass but I still don't get how to get the force from the fulcrum?
Homework Statement
The beam is 47 cm in length. The other length measurements are R1 = 11 cm, and r2 = 26cm. The mass of the beam is 6.0 kg. Determine the mass on the beam.

Homework Statement
The question is- What is the minimum coefficient of static friction that would keep the car from sliding off the curve? The Cars mass is 13500KG and it is traveling at 50.0hm/hr(13.9m/s) and the curve has a radius of 2.00 x102 m. I know the centripetal acceleration of the car...
