A paper mill processes rolls of paper having a density of 984 kg/m3. The paper roll is 1.50 m outside diameter (OD) x 22 cm inside diameter (ID) x 3.23-m long and is on a simply supported, hollow, steel shaft. Find the shaft ID needed to obtain a maximum deflection at the center of 3 mm if the shaft OD is 22 cm. Assume the shaft to be the same length between supports as the length of the paper roll.

Three-point bending test was performed on a glass specimen : A three-point bending test was performed on a glass specimen having a square cross-section of 15 mm length on each edge. The specimen fractured at a load of 4770 N when the distance between the support points was 41 mm.

Reduce crack length and increase tip radius : The fracture strength of glass may be increased by etching away a thin surface layer. It is believed that the etching may alter the surface crack geometry (i.e. reduce crack length and increase tip radius). Calculate the ratio of the etched and origi..

Determine temperature in celsius of equilibrium ice water : Estimate the slope dp/dt of the ice +water line using the triple point information. Specific entropy of ice at the triple point is -1221J/kgK , specific entropy of liquid water at triple point is 0.0 J/kgK. Determine therefore the temperature in Cels..

Specific heat at constant pressure of the saturated liquid : Show that the specific heat at saturation of a liquid phase of mass m (defined by Cf= (deltaQ/m)dt is generally not the same as the specific heat at constant pressure of the saturated liquid.

Same length between supports as the length of the paper roll : A paper mill processes rolls of paper having a density of 984 kg/m3.

Create a segment of a recognizable tune consisting : Create a segment of a recognizable tune consisting of 5-6 notes, possibly with spaces in between. Search web sources to find the frequencies of familiar music notes (for example the frequency of A4 is 440Hz, of A5 is 880Hz, of C5 is 523.25Hz).

Relationship between independent variables and deflection : The bottom of a large, 5-gallon plastic bucket bows when the bucket is filled with water. The deflection of the bottom surface, ?, is a function of the bucket diameter, D, the depth of water, h, the specific weight of the water, ?, the thickness of t..

Heat transfer coefficient between water and surroundings : A hot-water cylinder contains 150 liters of water. It is insulated, and its outer surface has an area of 3.5 m^2. It is located in an area where the ambient air is 250C, and the overall heat transfer coefficient between the water and the surroundings..

Determine the actual heat transfer rate : A shell and tube heat exchanger with one shell pass and four tube passes is being analyzed to determine the heat transfer rate and the fluid outlet temperatures for prescribed flow rates and inlet temperatures. The cold fluid has a heat capacity rate..
