A hollow shaft has an internal diameter of 58 mm and a wall thickness of 4.7 mm Calculate its polar second moment of area, J. Input your answer in units of 10A-9 mA4 to 2 decimal places. So, for example, if J is found to be 530.6x10A-12 mA4, you should input 0.53 as your answer.
A hollow cylindrical shaft has an internal diameter of 54 mm and a wall thickness of 4.7 mm. Calculate its polar second moment of area, J. Input your answer in units of 10^-9 m^4 to 2 decimal places. So, for example, if J is found to be 530.6x10^-12 m^4, you should input 0.53 as your answer.
1) Diameter of a coin is measured as 0.223 cm and its height (thickness) is measured as 0.024 cm and weight 5.3 grams. Calculate density of the coin and compare it with the density of copper 8.96 gr/cm3 . Could your coin be pure copper? What is the precision for each measurements 2) In a free fall experiment, when you plot height in meters versus time squared as second squared, you obtain your slope as 4.8. What is the unit...
