An aluminum cylinder with a radius of 2.7 cm and a height of 67 cm is used as one leg of a workbench. the workbench pushes down on the cylinder with a force of 3.2×104n. what is the compressive strain of the cylinder? young's modulus for aluminum is 7.0×1010pa. express your answer using two significant figures. compressive strain = nothing
by what distance does the cylinder's height decrease as a result of the forces on it?

Explanation:

r = Radius = 2.7 cm

F = Force =

A = Area =

= Stress =

E = Young's modulus =

= Strain

= Original length = 67 cm

= Change in length

Young's modulus is given by

Strain is

Strain is given by

The cylinder height decreases by

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
