Solve A and B:
A: What are the two most important criteria that need to be met for a material to undergo creep?
B: From the log (deflection) vs. log (time) results from a creep
experiment with plastic wood, the slope calculated is 0.025.
Determine the creep exponent and its error.
Homework Answers
a) Creep is the natural tendency of a material to gradually move or permanently deform as a result of mechanical stress.
Parameters effecting creep:
- Temperature: Creep in service is usually affected by changing conditions of temperature
- Stress:Changing conditons of loading
The creep mechanism if different for metals ,plastics , wood etc.

6.) P-values: First, and most important, what is a p-value? A p-value is the probability of getting the sample results IF the null hypothesis is true. This is the definition of a p-value. VERY IMPORTANT: A p-value is NOT the probability of the null hypothesis being true. If you remember only one statistical thing from this exam, please remember this idea regarding p-values. Also, look into the following regarding p-values: a.) How are they calculated? b.) How are they used...

A student conducted an experiment to determine what factors are important in the rate of reaction between potassium carbonate and hydrochloric acid. The student diluted 4.000 mL of 4.000 M K2CO3 to 150.0 mL, then combined that solution with 150.00 mL of 2.000 M HCl at an increased temperature of 50 °C. The student tabulated the amount of CO2 gas collected over time and recorded the results in the columns to the left. 1. Use a rearrangement of PV =...

solve using paython
In fluid flow problems, the flow velocity in a long horizontal pipe depends on the pipe material, pipe geometry and fluid properties in addition to the pump power. For a horizontal pipe with a pump, the friction factor can be obtained from many correlations such as Colebrook-White Equation: 1.1998 5.0452 (6) log Re 28257 -)} (1) 3.7065 7--2 log +58506 (Re)-0.3981 In which, f is the friction factor and is the roughness ratio given by: given by:...
