Acopper (shear modulus 4.2 x 1010 n/m2) cube, 0.242 m on a side, is subjected to two shearing forces, each of magnitude f = 3.07 x 10 6 n (see the drawing). find the angle (in degrees), which is one measure of how the shape of the block has been altered by shear deformation.

The angle is 0.00124°.

Explanation:

Given that,

Shear modulus

One side of copper = 0.242 m

Shearing forces

We calculate the angle

Using formula of shear modulus

F = force

A = area

S = shear modulus

Put the value into the formula

Hence, The angle is 0.00124°.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
