Determine the magnitude and coordinate direction angles of the resultant force. 0.75 m FAR = 250 N FAC = 400 N 3 m * 40°~2 m B 2 m fim-

Please explain how the moment of FAB and FAD were calculated in this picture. For example, I dont know where (0.24i and 720j) came from in calculating for FAB. I also dont know how -172.8 and 74.051 were obtained. Please explain it because I want to understand how to calculate for these two moments. The original item and diagram are shown on the right.

Hello, I need your help.    Topics: Force System of a Force, Moment of a Force, Moment of a Force-Scalar Formulation, Moment of a Force-Vector Formulation, and Principle of Moment.   Note: Kindly show the complete step-by-step solution. Please make sure that your handwriting is understandable and the picture of the solution is clear. I will rate you with “like/upvote” after. Thank you so much.

Barry enjoys doing bicep curls at the gym. In a bicep curl, Barry's forearm is rotated around his elbow, due to a torque generated by his bicep muscle. In figure 1 we have two lines representing Barry's shoulder, upper arm, elbow and forearm. Shoulder U pper Arm Elbow Forearm Figure 1: Barry's shoulder, upper arm, elbow and forearm. (a) Barry's bicep muscle connects from his shoulder to a point on his forearm, 4 cm from his elbow . His bicep makes an angle of 85° with his forearm . Draw a line on the diagram above to represent Barry's bicep. Make sure the distance from the elbow to the bicep connection with the forearm, and the angle between the forearm and bicep are also shown. (b) Barry's bicep can generate a force of 100 N - in the direction of the bicep - from the point the bicep connects to the forearm, to the point it connect with the shoulder. i) Calculate the components of the force Barry's bicep muscle is creating that are parallel with (F), and perpendicular to (F1), his…
