Prove that the COP of a reversible refrigerator operating between two given temperature is the maximum.
A) Name some risks which Spiral Model can identify and resolve?
B) Is the number of loops present in the Spiral Model fixed? If yes, write
down the number of loops the spiral model has. If the answer is no, then
explain how and on what basis the number of loops of the spiral can be
determined with the help of a well labelled schematic diagram
2. A steel clip angles are commonly used to transfer loads from horizontal girders to vertical columns. If the reaction of the girders upon the angle is a downward force of 45kN and if two 22mm diameter rivets resist this force, find the average shearing in each of the rivets. Assume that the rivet fills the hole.
3. Figure shows the singly symmetrical cross-section of a thin-walled open
section beam of constant wall thickness t, which has a narrow
longitudinal slit at the corner 15. Calculate and sketch the distribution of
shear flow due to a vertical shear force S acting through the shear centre,
S and note the principal values .Also determine the position of shear
center. (10)
4. Draw the shear flow distribution for the cross-section shown in figure.
1. Determine the Moment of inertia for the singly-symmetrical cross-section.
find the general solution of the given DE (x - 2y)dx - (x - 2y + 1)dy = 0
The 8-bit registers R1, R2, R3, and R4 initially have the following values:
R1 - 1111 0010, R2- 1 1 1 1 1 1 1 1 , R3- 1011 1001 , R4 1 1 101010
Determine the 8-bit values in each register after the execution of the following sequence of
microoperations.
R1 <-R1 + R2
R3<- R3 ^ R4, R2 <- R2 + 1
R1 <- R1 – R3
1. Determine the Moment of inertia for the singly-symmetrical cross-section
shown in figure. (5)
2. The thin-walled beam section shown in Figure is subjected to a bending
moment M applied in a negative sense. Find the position of the neutral
- axis and the maximum direct stress in the section.
A simply supported 6m long I beam in a structure you are working on requires the deflection in the center of the beam to be limited to 7 X 10 -6m and the slope to be limited to 5.5x10 -6 . It carries a maximum point load of 15kN in the center of the beam. Review a suitable size universal beam from the data table given to suit the design specifications.
