Well I am looking for same answer and what I found out is if there is not a conrete example that you actullay tried to solve there is not much help on the basics on this forum...

are there any rules/formulas regarding centroids of certain geometric shapes ?

:( thanks for help

can someone please help me need to do this by tomorrow :(

ok here is how I attempt to solve the case Take a look at the pic step 1 regarding 3) Since there is no mass on "wheel" F(res) = m(wheel) * a = 0*a = 0 step 2 regarding 3) K = \sqrt{}((SxS)+(SxS) = \sqrt{}2 * S step 3 regarding 1) Newtons 2. in x direction gives S - R = Ma y...

You mean like this ?

heres the pic to describe prob

Homework Statement Blocks A and B have mass of Ga and Gb respectively. Wire has no mass, it starts moving so that B has constant speed downward Homework Equations 1.Find μ (frictionkoeficient) regarding GA og GB. 2.When system start moving a cat with weight Ga jums on block A and system...

anyone familiar with this ?

Hi Jay thanks for help :9 Ok here we go again 1) G2x = G * sin45 = 1100 * 0,707 = 777,82 N => G2x = G2y = N2 2) Ff2 = 0.30 * 777,82 = 233, 35 N 3) SUM Fx=0 for B1 => +Ff2 +G2x - F2 => F2 = 777,82 + 233.35 = 1011,17 N 4) G1x = G * sin30 = 450 N 5) G1y = G* cos30 = 779,42 N => G1y = N1 3)...

Homework Statement 2 blocks are connected with wire each on its own angle area. Body 1 (B1) has weight 900N, angle 30, µ = 0,35 B2 wight = 1100N, angle 45 and µ=0.30 There is no friction on at the T ( picture ) How big F has to be to pull block1 down following shown path? Homework...

ok nvn did png upload :) 4 is not horisontal roller. Its the same as A. did support forces directly on main pic with brown color since image will be to large...

ok I asked someone more expirienced to help me with this problem and he defined it in a really simple metter. I will leave this picture as example if anyone encounters same kind of problems :) Thanks to doc and nvn who sent my toughts in right direction... Actually doc explined it in one of his...
