AI Thread Summary
The discussion focuses on solving a torque problem involving a uniform picture frame weighing 10N, supported by two cords. One cord is vertical while the other makes a 50-degree angle with the horizontal. Participants suggest breaking down the forces into X and Y components to find the tension in the cords and the horizontal force F. A recommended approach is to choose the upper right corner of the frame as the pivot point to simplify calculations. The conversation emphasizes the importance of selecting an effective pivot to streamline the torque equations.

1. A uniform picture frame weighing 10N is supported. The cable on the right side makes an angle of 50 with the horizontal direction. Find the tension in the cords and the magnitude of the horizontal force F required to hold the frame in the position

Homework Equations


imagine a rectangular box, the length is 0.15m and width 0.3m there is a cord hanging on straight up from the top left of the box and a cord hanging on the top right of the box at a 50 degree angle. Also there is a force F pointint to the left from the bottom right corner


The Attempt at a Solution


i believe this question is a torque question, but I'm not 100% sure how to start solving. i broke down the equation into X-component and Y-component
X-comp: fcos50 - F =0
Y-comp: fsin50 + f(left) = 10

i'm kinda stuck after this point
i know that torque = Fd but i don't know where my pivot point should be and so on can anyone help. thanks!

You can choose any point for the torque pivot... It's best to choose a point that makes your equations simple...

I recommend the upper right point, because then you avoid having the trig stuff in your equation.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
