    Summation Torques
AI Thread Summary
The discussion focuses on deriving the summation of torques equation for an object in Figure P8.4, with the torque calculated about point O. The equations for the sum of forces in the x and y directions are established as ΣFx = -Rx + Fx = 0 and ΣFy = Fy + Ry - Fg = 0. The main challenge lies in determining the perpendicular distances from point O for the forces Fg, Fy, and Fx, with 'l' being the hypotenuse of a right triangle. Participants are seeking clarification on how to accurately calculate these distances to complete the torque equation. Understanding these distances is crucial for solving the torque summation problem effectively.

Homework Statement


Write the necessary equation of the object shown in Figure P8.4. Take the origin of the torque equation about an axis perpendicular to the page through the point O. (Let counterclockwise torque be positive and let forces to the right and up be positive. Use q for θ and Rx, Ry, Fx, Fy, Fg, l, and g as appropriate in your equations.)

For Fg,Fy and Fx, what are the perpendicular distances from O ? (Take the distance 'l' as the hypotenuse of a right angle triangle)
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
