(a)
Interpretation:
The sample having a high extent of cold working needs to be determined.
Concept Introduction:
Cold rolling is a process where the sheet is compressed and squeezed between rollers.
(b)
Interpretation:
The sample with minimum recrystallization temperature needs to be determined.
Concept Introduction:
Recrystallization temperature is a temperature at which grains within microstructure begins to transform.
(c)
Interpretation:
The sample having a high annealing temperature needs to be determined.
Concept Introduction:
Annealing is a process of heating a metal to a high temperature and cooling slowly at a subsequent rate. This process softens the metal.
(d)
Interpretation:
The sample with less annealing time needs to be determined.
Concept Introduction:
Annealing is a process of heating a metal to a high temperature and cooling slowly at a subsequent rate. This process softens the metal.

- Consider the following relational schema. An employee can work in more than one department; the pct_time field of the Works relation shows the percentage of time that a given employee works in a given department. Emp(eid: integer, ename: string, age: integer, salary: real) Works(eid: integer, did: integer, pct_time: integer) Dept(did: integer, budget: real, managerid: integer) Write the following queries in SQL: a. Print the name of each employee whose salary exceeds the budget of all of the departments that he or she works in. b. Find the enames of managers who manage only departments with budgets larger than $1 million, but at least one department with budget less than $5 million.arrow_forwardConsider the following schema: Suppliers(sid: integer, sname: string, address: string) Parts(pid: integer, pname: string, color: string) Catalog(sid: integer, pid: integer, cost: real) The Catalog relation lists the prices charged for parts by suppliers. Write the following queries in SQL: a. Find the sids of suppliers who charge more for some part than the average cost of that part (averaged over all the suppliers who supply that part). b. Find the sids of suppliers who supply a red part or a green part. c. For every supplier that supplies a green part and a red part, print the name and price of the most expensive part that she supplies.arrow_forwardThe following relations keep track of airline flight information: Flights(flno: integer, from: string, to: string, distance: integer, departs: time, arrives: time, price: integer) Aircraft(aid: integer, aname: string, cruisingrange: integer) Certified(eid: integer, aid: integer) Employees(eid: integer, ename: string, salary: integer) Note that the Employees relation describes pilots and other kinds of employees as well; every pilot is certified for some aircraft, and only pilots are certified to fly. Write each of the following queries in SQL.(Additional queries using the same schema are listed in the exercises for Chapter 4) a. Identify the routes that can be piloted by every pilot who makes more than $100,000. b. Print the name and salary of every nonpilot whose salary is more than the average salary for pilots. c. Print the names of employees who are certified only on aircrafts with cruising range longer than 1000 miles and who are certified on some Boeing…arrow_forward
- Develop a signal design and timing for the intersection shown in the figure below. In each case accommodate both vehicular and pedestrian movements. In general, use the following values for the problem: pedestrian walking speed = 1 [m/s], vehicle deceleration = 3 [m/s²], driver reaction time = 1.5 [s], length of vehicle = 6 [m], and level grade = 0. If you need to assume other variables and parameters to solve this problem clearly state that in your report and explain the reason. = 4250 1100 70 1100 80 One-way ' 1 900 Speed limit = 50 [km/h] Pedestrian = 15 per each crosswalk Crosswalk widths = 3 [m] Lane width = 4 [m] Saturation flow = 1800 [veh/h/lane] 200arrow_forwardQu 1 If crank OA rotates with an angular velocity of ω = 12 rad/s, determine the velocity of piston B and the angular velocity of rod AB at the instant shown. please show all workarrow_forwardQ2/ Maria has an online shop where she sells hand made paintings and cards. She sells the painting for 50 and the card for 20. It takes her 2 hours to complete 1 painting and 45 minutes to make a single card. She also has a day job and makes paintings and cards in her free time. She cannot spend more than 15 hours a week to make paintings and cards. Additionally, she should make not more than 10 paintings and cards per week. She makes a profit of 25 on painting and 15 on each card. How many paintings and cards should she make each week to maximize her profit.arrow_forward
