1. The problem statement, all variables and given/known data Use the graphical and trigonometic solutions to calculate the total muscle force vector from thefollowing three quadriceps muscles i) rectus femoris pulling 75 N at 5°laterally from the vertical, ii)vastus lateralis pulling 50 N at 30°laterally from the vertical, and iii) vastus medialis pulling 45 N at 40° medially from the vertical. 2. Relevant equations i used basic trig to solve for each vector 3. The attempt at a solution I got all vertical and horizontal components for each vector for the 75N at 5 degrees i go 75 horizontal and no vertical for the 50N at 30 degrees i got 25 vertical and no horizontal for 45N at 45 degrees i got 28.9 vertical and 34.5 horizontal i added all the vertical and horizontal square rooted to get the resultant and was of by 10, so where or what did i do wrong ?
