Automobile Engineering

Using s,v,a,j diagrams, determine if the polynomial listed below results in a satisfactory cam design. You must state the reason and show work to support your answer.
s=C_{0}+C_{1}(\theta / \beta)+C_{2}(\theta / \beta)^{2}
Where Co, C1, C2 and B are constants. At the end of the low dwell, s = 0 and0 = 0 and at the beginning of the high dwell s = h and 0 =B.

Question 36484

Automobile Engineering

A manufacturing industry using 50 servicingequipment similar to the equipment presented infigure 1. The servicing equipment is composed of fivesubsystems. The estimated reliability for eachsubsystem is:
Subsystem A is 0.99
Subsystem B is 0.81
Subsystem C is 0.75
Subsystem D is 0.98
Subsystem E is 0.90
To estimate the related Annual Maintenance Cost,the servicing equipment have been tested. The record of breakdowns during the testing period is presented in the table below:
Annualized Maintenance Cost by 30%. So, they decide to contract out the preventive maintenance to a service company SERVISCO. The contract will include fixed fees of 50 KD and the cost of:
- Labor: 30Kd
Consumables: 5KD
Before signing the contract, the manufacturer performed a trial period with SERVISCO company,the new record of breakdowns presented by this company is shown below:
1-Calculate the system reliability
2-Calculate the corrective maintenance cost per month
3-Calculate the new maintenance cost if the plant will contract out the preventive maintenance service
4-Calculate the expected Annualized Maintenance Cost before and after contracting the maintenance service
5-Give the expected annual savings in maintenance cost
6-Will the firm contract out the preventive maintenance service with this company? To answer this question , you have to calculate the targeted budget.
