- Replace the loading (F1 and F2) by an equivalent resultant force and couple moment at point A. Enter your responses in the blanks provided. Upload your workings. What is the magnitude of the resultant force? Enter your response in Newtons to three significant figures.arrow_forwardAssume the image below is your arm and you are lifting a 15 lb weight. your arm is now at a 50-degree angle to your body. The force from the muscle is vertical. The weight of your arm is 5 lbs. dbiceps is 2cm and dball is 6cm. Please draw a free body diagram of the arm at that 50-degree angle with the forces. What is the force that the muscle puts on the arm? What is the force from the muscle if the weight is all the way up?arrow_forward
