You drop a steel ball bearing, with a radius of 3.40 mm, into a beaker of honey. Note that honey has a viscosity of 4.00 Pa/s and a density of 1360 kg/m3, and steel has a density of 7800 kg/m3. Assume that g = 9.8 m/s2.
Aluminum has a density of 2700 kg/m3. What radius should an aluminum ball have to have the same terminal speed in honey that the steel ball has?

A stainless steel ball bearing has a radius of 6.35 mm and a denisity of 7.75 g/cm^3. Iron is the principle element in steel while carbon is a minor element. The ball bearing contains 0.25% carbon by mass. Assuming that the percent isotopic abundance for ^13 C is 1.108%, how many iron ^12 C and ^13 C are present in the ball bearing
Element 1 is a steel bar that has a circular cross-section with a radius of 30 mm. Element 2 is an aluminum bar that has a circular cross-section with a radius of 50 mm. Element 3 is a steel bar that has a circular cross- section with a radius of 60 mm. Assume for steel, the moduļus, E, is 2.0E11 Pa, and the density, p, is 7800 kg/m3. Assume for aluminum, E-7.0E10 Pa, and p-2700 kg/m3. The rigid, massless rod...
in this lab we will drop a steel ball P steel=8000 kg/m^3, r ball=2.18x10^-3) through the air (nair=1.8x10^-5 Pas, P air= 1.29kg/m^3) and through a viscous soap solution (n soap ~ 9.0 Pa s) you will measure this number in lab, but use this number for prelab.( P soap = 1000kg/m^3) 1Pa= 1N/m 1. (a) assuming that the ball falling through the soap solution experiences visocus drag, find the terminal speed of the ball, the speed at which the weight...
A stainless steel ball (radius rsphere = 0.3175 cm, density ρsphere = 7.866 g/cm3) falls through a viscous fluid (density ρfluid = 1.2 g/cm3) and quickly reaches terminal speed v. You measure the ball’s position as a function of time to find v. The ball is at positions y = 10 cm at time 2.402 and at position y = 5 cm at time 3.26. Calculate the viscosity η of the fluid in units of poise = g/(cm-s), using your...
1. A block of aluminum that has dimensions 1.16 cm by 3.00 cm by 5.00 cm is suspended by a thread from a spring scale. Density of aluminum is 2702 kg /m3. A beaker full of oil (density 8.50 × 105 g/cm3) rests on a second scale, which reads 460.0 g. The block is then lowered so it is fully submerged in oil without touching the bottom of the beaker. What is the reading on the spring scale supporting the...

4. Hardening of ball bearings made from Type 440C stainless steel, one of the hardest stainless steels, is accomplished by heating the bearings to 1010 to 1065 °C then quenching (rapidly cooling) them in oil Consider bearings 24 mm in diameter at an initial uniform temperature of 1050 °C, cooled in an oil bath at 50 °C in which the convective heat transfer coefficient is 600 W/(m2 K).

A patient in the hospital is receiving a saline solution through a needle in their arm. The needle is 2.20 cm long, horizontal, with one end in a vein in the arm, and the other end attached to a wide tube that extends down from the bag of solution, which hangs from a pole so that the fluid level is 90.0 cm above the needle. The inner radius of the needle is 0.250 mm. The top of the fluid is...
