What Forces Do Stepladders Exert on a Plank Supporting a Painter?

AI Thread Summary
To determine the forces exerted by each stepladder on a plank supporting a painter, the problem involves analyzing static equilibrium and torque. The painter's weight of 875N and the plank's weight of 223N must be balanced by the forces from the stepladders. The painter stands 1.0m from one end of the 3.0m plank, creating a torque that needs to be calculated to find the forces. A diagram can help visualize the forces and moments acting on the system. Understanding the principles of torque and static equilibrium is essential for solving this problem effectively.

A painter weighing 875N stands on a plank 3.0m long, which is supported
at each end by a stepladder. The plank weighs 223N. If the man stands 1.0m from one end of the plank, what force is exerted by each stepladder?

ANSWER: 694.8N ; 403.2N -> (ans provided by my hand-outs)

Q
1. how to solve?
2. does dis have a pivot point pls help...

Thank you very much 4 helping...

Please show what you've tried. That's the rule you've agreed to when you registered to physicsforums.

If you have no idea what to do, I stongly suggest reading the relevant chapters from your physics book.

Start by drawing a diagram.
 
cant really understand...
the only example the teacher gave 2 me was..
the seesaw thingy & the equilibrium
can u gve me a hint plss...

does dis have to do about torque or static equilibrium...

Thread 'Errors and significant figures'

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...
