BIO Heart repair . A 5urgeon is using material from a donated heart to repairs patient's damaged aorta and needs to know the elastic characteristics of this aorta material. lasts performed or. a 16.0 cm strip of the donated aorta reveal that it stretches 3.7E cm when a 1.50 N pull is exerted on it (a). What is the force constant of this strip of aortal material? (b) If the maximum distance t will be able to stretch when it replaces the aorta in the damaged heart is 1.14 cm, what is the greater: force t will be able to exert there?

A 1520-N crate is to be held in place on a
ramp that rises at 30.0° above the
horizontal (see figure). The massless rope
attached to the crate makes a 22.0° angle
above the surface of the ramp. The
coefficients of friction between the crate
and the surface of the ramp are
uk = 0.450
and
ls = 0.650
The pulley has no appreciable mass or
friction. What is the MAXIMUM weight w
that can be used to hold this crate
stationary on the ramp?
w = ?

Calculate the force (in N) a piano tuner applies to stretch a steel piano wire 8.20 mm, if the wire is originally 0.850 mm in diameter and 1.35 m long. N t
8. A factory needs to move packages from one level to another using a ramp. They want to choose a material that has a specific coefficient of friction with the packages that will be sliding down the ramp.
a) What problem could occur if the coefficient of friction were too high?
Your answer:
O Packages would go too fast and could break at the end of the ramp.
O Packages could slow down too quickly and stop before the end of the ramp.
O Packages could break the ramp because gravity would increase.
O Packages could bounce off the ramp because normal force would increase.
