i used the quation M= r X F where OP=r = -i -2j then i get M = (-i - 2j) X F i don't know what to do after that to find F

Homework Statement A 2-dimensional force of 5[units] in the direction of the line y = 3x (upwards) acts through the point P = (−1,−2). Find the moment of the force about the origin Homework Equations M = Fd The Attempt at a Solution i tried putting x = -1 and y = -2 into the y=3x...

i don't know the equation for the 2nd question

is the equation d = square root of [(x2-x1)2 + (y2-y1)2 + (z2-z1)2] for the 1st question?

Homework Statement Im stuck on a few questions i can't seem to find the methods in my notes. the questions are: 1.The points P, Q, and R have coordinates P = (1, 0,−1),Q = (1,−2, 5) and R = (0,−3, 2). State which pair of points are closest to each other. 2.A 2-dimensional force of...

i know that dude but i don't understand how to put the q line on the graph? i kno its going to haev a negative gradient but i don't understand on how plot it. i think u put the Xf going up to the 45 degree line then from there what do i do?

hi guys ive been given a problem and I've worked most of it out but I am not sure whether my answer for the feed line (q) is correct can i get somebody to re assure me on how to plot it onto the graph and get it correctly. here's the question below. A mixture containing 40 mole% heptane and...
