density = 1000 volume = 0.6 x 0.020 x 1.0 answer = 0.6 x 0.020 x 1000 x 10 = 120N/m can someone please explain to me why you have to times it by 10 at the end to get 120n/m i understand the equation just don't understand the x 10 part at the end.

yes i meant 118 sorry about that

well -188 +FsinA = 0 is the same as writing -188 +Fcos(90-A) = 0 since its sin it means it is the verticle but this does not mean that Fy will always be the verticle if you in a situation where Fx has to be sin0 then fx will be the verticle and it would be 101.33/118 instead of...

if you need further explanation let me know

-101.33 + (theforce)cosA = 0 -188 + (theforce)sinA = 0 tanA = -188 / -101.33 therefore A = 49.35 degrees to the horizontal

the force that give you equilibrium is 155.55N and its direction is 49.35 degress to the horizontal

thank you so much i swear to god if i had a credit card i would pay you 5 dollers

yes that is correct there is actually a third equation that when combined with the first two equations gives all the answers the third equation is 2Vb - 3Hb = -26 the final answers are Vb = 26.2 Hb = 26.1 FAC = 32.4 The problem i have is that i don't understand how the...

the answer i got myself was 1.732Vb - Hb = 12 i got no idea how they got 19.32

basic algebra question please help :( when combining the two equations Vb-0.5FAC = 10 Hb -0.866FAC = -2 It brings the answer 1.732Vb - Hb = 19.32 can someone plx explain to me how this answer came about

could somebody please help me the two equations are Vb -0.5FAC = 10 Hb -0.866FAC = -2 some how by combinding these two equations give the answer 1.732Vb - Hb = 19.32 Could somebody please explain to me how this is so?
