Question About Resultant of Parallel Forces

AI Thread Summary
The discussion focuses on finding solutions for problems related to the resultant of parallel forces. Key formulas for determining the resultant include calculating horizontal and vertical components (Rx and Ry), the moment (Rd), and the overall resultant (R) using the Pythagorean theorem. Participants are encouraged to post their work for review and seek clarification on any mistakes. The thread emphasizes the importance of peer feedback in understanding the concepts. Engaging with others to verify calculations is essential for mastering the topic.

i want to know the solution for this problems
some of the problem has a answer already but no solution...

Summary of Formulas for Determining Resultant of non concurrent force systems.

Rx = ∑ Fx horizontal component of the resultant
Ry = ∑ Fy vertical component of the resultant
Rd = ∑ M ( MOMENT )
R = √ (Rx)^2 + (Ry)^2

tan θ = Ry / Rx

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'

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...
