Answer:
a) (option B) 230 kPa
b) (option A) 100 N/m
Explanation:
Given:
Diameter, d = 25 m
Thicknesses, t = 15 mm
Yield point = 240 MPa
Factor of safety = 2.5
a) To find the maximum internal pressure, let's use the formula:
Solving for P, we have:
P = 230.4 kPa
≈ 230 kPa
The maximum permissible internal pressure is nearly 230kPa
b) Given:
Thickness, t = 6.35 mm
L = 203 mm
Torque, T = 8 N m
Let's find the mean Area,
mA = (l - t)²
= (203 - 6.5)²
= 38671.22mm²
≈ 0.03867 m² (converted to meters)
To find the average shear flow, let's use the formula:
q = 103.4 N/m approximately 100N/m
The average shear force flow is most nearly 100 N/m
Answer:
a) Decreasing grain size decreases the amount of possible pile up at the boundary, increasing the amount of applied stress necessary to move a dislocation across a grain boundary. ... Grain sizes can range from about 100 μm (0.0039 in) (large grains) to 1 μm (3.9×10−5 in) (small grains).
b) Solid solution strengthening is a type of alloying that can be used to improve the strength of a pure metal. The technique works by adding atoms of one element (the alloying element) to the crystalline lattice of another element (the base metal), forming a solid solution.
c) Work hardening, also known as strain hardening, is the strengthening of a metal or polymer by plastic deformation. ... This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material.

Answer:
The following query is used to display TripName. Reservationld, FirstName. LastName and TotalCost of trip by adding the trip price plus other fees and multiplying the result by the number of persons which have number of persons >4.
Query:
SELECT ReservationlD, Trip.TripName. Customer.LastName. Customer.FirstName. (TripPrice+OtherFees) 'NumPersons as TotalCost FROM Reservation, Trip, Customer WHERE NumPersons>4 AND Reservation.TriplD=Trip.TriplD AND
Customer. CustomerNum=Reservation.CustomerNum:
Explanation:
- Select clause is used to retrieve data from specified database table or relation and returns the data in the form of table.
- ReservationID. Trip.TripName. Customer.LastName. Customer.FirstName are the column name of table.
- (TripPrice+OtherFees) 'NumPersons will calculate the total cost of the Trip and stored it into TotalCost column.
- As clause is used to give new name TotalCost to resultant column.
- FROM clause specifies one or more table from where records to be retrieved. o Reservation. Trip and Customer are the table name.
- WHERE clause is used in SQL query to retrieve only those records that satisfy the specified condition
