    Torque Angles

    I can't do this? sum of Fx = FL*cos(thetaL) - FR*cos(thetaR) FR = [FL*cos(thetaL)] / cos(thetaR) Plug into 0 = FR*r*sin(84) + FL*r*sin(44)

    Torque Angles

    Like you said before, I need another equation to solve for FL and FR. I think I can use the summation of Fx or that of Fy, correct? If it's no trouble to you to explain to me about the angles after you've figured it out, I would really appreciate that. Thank you so much for everything so...

    Torque Angles

    I'm sorry too! I titled it this way because this is a part of a lab involving torque. I'm confused as to why they put in a problem that has little to do with the hardcore concept of torque itself too. Just out of curiosity, could you explain to me how I would do it with torques? The entire...

    Torque Angles

    I'm sorry but I don't quite understand. The tensions aren't equal and yet I need to equate them? Plus, how can I know the vertical force without having the tension? If the bar isn't moving then there are no forces at work so why aren't the tensions equal at least in their x and y components...

    Torque Angles

    I was going to find the tensions using the fact that the sum of Fx and sum of Fy are 0 N in equilibrium. So I wanted to solve for the right tension in terms of the left. But I guess it would be easier to set the sum of the torques equal to 0 instead. Is 16 the angle of the gravitational force...

    Torque Angles

    http://img.photobucket.com/albums/v495/lizology101/physicsproblem.jpg?t=1205375687" [Broken] I know the process to solve the problem but I don't understand what I'm supposed to do with the 16 angle. Aren't the other angles already measured to the horizontal plane of the axis of rotation? If...
