hand, with the forearm weight of Fa. If... • the forearm weight (Fa) is 40 N, forming an angle (theta) with the forearm of 65 degrees as shown. This force is located 14 cm (da) from the elbow (note that this distance is NOT perpendicular to the force). • the dumbbell weight (Fw) is 184 N, forming an angle (theta) with the forearm of 65 degrees as shown. This force is located 39 cm (dw) from the elbow (note that this distance is NOT perpendicular to the force). • the muscle force (Fm) forms an angle (theta) with the forearm of 60 degrees as shown. This muscle inserts into the forearm 5 cm from the elbow. ... then what is the muscle force (Fm), in N, required to hold this static position?

Q19

The diagram shows a muscle force (Fm) required to hold a weight (Fw) in the hand, with the forearm weight of Fa. If... • the forearm weight (F₂) is 40 N, forming an angle (theta) with the forearm of 65 degrees as shown. This force is located 14 cm (da) from the elbow (note that this distance is NOT perpendicular to the force). • the dumbbell weight (Fw) is 184 N, forming an angle (theta) with the forearm of 65 degrees as shown. This force is located 39 cm (dw) from the elbow (note that this distance is NOT perpendicular to the force). • the muscle force (Fm) forms an angle (theta) with the forearm of 60 degrees as shown. This muscle inserts into the forearm 5 cm from the elbow. ... then what is the muscle force (Fm), in N, required to hold this static position?
