CP A Foucault pendulum consists of a brass sphere with a diameter of 35.0 cm suspended from a steel cable 10.5 m long (both measurements made at 20.0°C). Due to a design over-sight, the swinging sphere clears the floor by a distance of only 2.00 mm when the temperature is 20.0°C. At what temperature will the sphere begin to brush the floor?

a). At what temperature will the sphere begin to brush the floor?
A Foucault pendulum consists of a brass sphere with a diameter of 31.0 cmcm suspended from a steel cable 11.5 mm long (both measurements made at 20.0∘C∘C). Due to a design oversight, the swinging sphere clears the floor by a distance of only 3.00 mmmm when the temperature is 20.0∘C∘C.
Part A
At what temperature will the sphere begin to brush the floor?
A student foolishly attempts to stop a steel bar, of length L = 1 m and at a temperature of 20ºC, from thermally expanding by attaching it to a wooden support with a nail at each end. Steel's Young's modulus is Y = 1.1 × 1011 N/m2 and it's linear thermal expansion coefficient is α = 13 × 10-6 1/C. Randomized Variables
Y = 1.1 × 1011 N/m2α = 13 × 10-6 1/C
What is the volue of the stress, in pascals, that develops due to a rise of temprature to 21 C?
Assuming the nails have a cross- sectional area of A= 10^-5 m^2 all of which is perpendicular to the stress force from the bar, what is the force acting on each due to that temperature rise?
