Question: a capo is used to compress strings on a guitar...

Question details

A capo is used to compress strings on a guitar and change its tuning(see Figure).Coordinates are given in mm.

a)Draw a free body diagram of the top part of the capo (containing points A, B, D) when it is squeezed with forces as shown.

b)Draw a free body diagram of the bottom part of the capo (containing points (A, C, E).

c)When the capo is squeezed with a force 20 N and angle 30°, what is the magnitude and angle (θ) of the force F?

d)What is the magnitude of the force at B from the spring?

e)What are the x-and y-components of the force at A?

f)Draw a free body diagram of the top part of the capo after it is applied to the guitar and released (see Figure)
