4.Considering both temperature and pressure to be variables, what is the largest number of phases that can coexist at equilibrium in a binary alloy?

## Calculate the size of the mass m so that block a slidesThe 2kg block A and the 5kg block B are initially at rest on the inclined plane at 20 degrees. All surfaces in this system have a coefficient of static friction of 0.6 , and a coefficient of kinetic friction of 0.4. |

## How the strains deform the element within the x-y planeUse the strain-transformation equations to determine (a) the in-plane principle strains and (b) the maximum in-plane shear strain and average normal strain. |

## What is the reaeration coefficient if it is assumed that noYour other assistant is measuring the propane (C3H8) concentrations, which are 75 microM at 200 m downstream and 52 microM at 1500 m downstream. What is the reaeration coefficient if it is assumed that no dilution occurred due to lateral flow? |

## At what load would you expect the specimen to fractureThree-point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 5.5 mm; the specimen fractured at a load of 850 N when the distance between the support points was 50 mm. |

## Find min acceptable wire diameter for max allowable stressA 200ft length of steel wire is to carry a tensile load of 340lb. Find the minimum acceptable wire diameter if the maximum allowable stress in the wire is 30ksi, and the lengh of the wire must not increase by more than 2 inches when there is no ch.. |

## What is the first order approximation for the mean of yLet X be a uniformly distributed continuous random variable ranging between 5 and 8, X ~ U[5 , 8]. Variable Y is a function of X: Y: h(X)= 2X^2+1 a. Determine the PDF of Y. b. Find the expected value of Y. |

## How to determine the lifetime risk of a residentConsider a small town in the Phillippines, where the average weight of people is 55 kg, and the average lifespan is 60 years. The people here eat lots of fish due to abundant availability from the local river. |

## Deriving the eom for buildingWorking a problem where there are two one-story buildings of different heights next to each other. Earthquake imparts a base motion z(t) that is a cosine function. I'm given a shape function for a column of height L when deriving the EOM for each .. |

## Determine length of the cable between the pulleys a and bCylinders C and D are attached to the end of the cable. if D has a mass of 600 kg, determine the required mass of C, the maximum sag h of the cable, and the length of the cable between the pulleys A and B. |

## How much heat energy is radiatred from each of the diskDuring frequent braking under race conditions the disk brake rotors on the car described above reach a temperature of 500C. These disk brakes rely on forced convection to cool them. The dimensions of each disk rotor are: outer radius 130mm |

## What input of power rating is required for pump to refillA water storage tank located on a larege dairy farm has a storage capacity of 0.1 ML. The average rate of water consumption from this tank is 6.25 kL per day, every day. The farmer refills the tank (overnight) every 14 days |

## Determine the net power delivered to the generatorAir enters the compressor at 98 kPa and 295 K at a rate of 10 kg/s and exits at 1 MPa and 620 K. Determine the net power delivered to the generator by the turbine. |
