The diagram shows a muscle force (Fm) required to hold a weight (Fw) in the hand. We are ignoring any forearm weight in this example. If... • the muscle force (Fm) is 1,901 N, forming an angle (theta) with the forearm of 50 degrees as shown. This muscle inserts into the forearm 6 cm from the elbow. • the dumbbell weight (Fw) is located 39 cm (dw) from the elbow (note that this distance is NOT perpendicular to the force). • The forearm is oriented 20 degrees from horizontal, as shown in the figure then what is the weight of the dumbbell (Fw, in N) held in this position? Report values to whole units (e.g. "101" for 101 N). You are allowed a margin of error of 15 N due to rounding.
