**factor of safety** Homework Statement Im having problems with this, any help would be much appreciated http://i826.photobucket.com/albums/zz190… The material for the bolt shown in the angled joint above has an ultimate tensile strength of 218 MPa and a shear of 230 MPa. The...

No I don't have the equ for direction of R. So u mean I need a single point where i takey moments from for all 4. Oh it's starting to make more sense now thankx. I'll have a go at it and reply with the result thankx

i think i got it now, caan u please comfirm that the following are corect and that all i need help with: The calculations for the 4kN M=F X D F Y = F Sin Ø = 4 Sin 45 = 2.82 F x = F Cos Ø = 4 Cos 45 = 2.82 ACM = F X D = 2.82 X 1 = 2.82 CM = F X D = 2.82 X 0 = 0 ∑ FX = 2.82 ∑ FY...

typing errors sorted, so where to now, can u please guide me on the 5kn

oh, the X axis is where the 6.93 comes from

thankx

and i believe the way of finsing the resultant force is: R^2 = (∑ FX )^2 + (∑ Fy)^2 R = √((∑ FX) ^2 + ((∑ Fy)^2 is that equation right

thankx for the explination however that was only a typing problem, anyway I am currently stuck on the 5kN fx and yx as it does not state an angle

and i also had a go at the 3 kN one. abd it turnd out as the following: M= F X D F Y = F Sin Ø = 3 Sin 0 = 0 F x = F Sin Ø = 3Cos 0 = 3 ACM = F X D = 0 X 0.5 = 0 CM = F X D = 3 X 0 = ∑ FX = 3 ∑ FY = 0 ∑ M = 0...

OK THANKX FOR THAT BIT, i re don it and came out with the following F Y = F Sin Ø = 8 Sin 30 = 4 F x = F Sin Ø = 8 Cos 150 = -6.93 ACM = F X D = 4 X 0.5 = 2 CM = F X D = -6.93X 0 = 0 sory i did not get ehat u ment after this bit

well i had a go at it, and this iss how it went: F Y = F Sin Ø = 8 Sin -30 = -4 F x = F Sin Ø = 8 Cos -30 = 6.93 ACM = F X D = -4 X 0.5 = -2 CM = F X D = 6.93X 0 = 0 (In FY and FX i put -30 angle cause the angle is acting anti clock wise) so what to next

the problem is i don't get the question, the first attempt is. the 4KN side. M=F X D F Y = F Sin Ø = 4 Sin 45 = 2.82 F x = F Sin Ø = 4 Cos 45 = 2.82 ACM = F X D = 2.82 X 1 = 2.82NA CM = F X D = 2.82 X 0 = 0 then i don't know where to go from there
