Calculating pressure of cylinder on table

AI Thread Summary
To calculate the pressure exerted by a cylindrical metal block on a table, the force is determined using the formula f = ma, resulting in a force of 313.6 N. The area of the cylinder's base is calculated as approximately 0.0005026 m². Using the pressure formula P = F/A, the initial calculation yields a pressure of 0.062470119 Pa, but this is corrected to 0.062395543 Pa. Further discussion reveals that the decimal placement in the final calculation was incorrect, leading to an inaccurate pressure value. Accurate calculations are crucial for determining the correct pressure exerted by the cylinder.

Homework Statement


A cylindrical metal block of mass 32 kg stands with its base on a horizontal table. The radius of the base of the cylinder is 4 cm. Calculate the value of the pressure on the table.


Homework Equations


Pressure = Force/Area


The Attempt at a Solution


f = ma, i don't know if this is where I am going wrong, but I am using acceleration due to gravity

(32)(9.8) = 313.6 N

area of bottom/base of cylinder = pi x 42 = 50.26 cm2

50.26 x 10-4 = 5.026 x 10-3 m2

P = F/A, so 313.6/5.026 x 10-3 = 0.062470119 Pa

yep, thanks in advance

Your powers of ten got mucked up in your final calculation.

\frac{313.6 N}{5.026 \times 10^{-3} m^2} = ?
 
yea, it should be 0.062395543

what now?

Your value is still incorrect. The digits are fine, but the decimal place is incorrect.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
