A crow bar having a length of 2.5m is used to balance a load of 750N. if the distance between the fulcrum and the load is 2m, CALCULATE. EFFORT, MA, VR,. n

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
