A cylindrical metal specimen having an original diameter of 11.34 mm and gauge length of 53.3 mm is pulled in tension until frac

ture occurs. The diameter at the point of fracture is 6.21 mm, and the fractured gauge length is 73.6 mm. Calculate the ductility in terms of (a) percent reduction in area (percent RA), and (b) percent elongation (percent EL).

WINSTONCH [101]3 years ago
5 0

Answer:

a) 70.29 %

b) 37%

Explanation:

percent reduction can be found from:

PR = 100*(π(do/2)^2-π(df/2)^2)/π(do/2)^2

     = 100*(π(11.34/2)^2-π(6.21/2)^2)/π(11.34/2)^2

     =70.29 %

percent elongation can be found from:

EL =L_f - Lo/Lo*100

    = (73.17 -53.3/53.3)*100

    = 37%

What are the steps to execute an instruction by cpu?What is the function of DMA controller.
JulijaS [17]

Explanation:

1. A sequence of instructions is stored in memory.

2. The memory address wherever the first instruction is found is copied to the instruction pointer.

3. The CPU sends the address within the instruction pointer to memory on the address bus.

4. The CPU sends a “read” signal to the control bus.

5. Memory responds by sending a copy of the state of the bits at that memory location on the

data bus, that the CPU then copies into its instruction register.

6. The instruction pointer is automatically incremented to contain the address of the next

instruction in memory.

7. The CPU executes the instruction within the instruction register.

8. Go to step 3

Steps 3, 4, and 5 are called an instruction fetch. Notice that steps 3 – 8 constitute a cycle, the instruction execution cycle. It is shown graphically below.

A DMA controller can generate memory addresses and initiate memory read or write cycles. It contains several hardware registers that can be written and read by the CPU. These include a memory address register, a byte count register, and one or more control registers.

An automobile having a mass of 1100 kg initially moves along a level highway at 120 km/h relative to the highway. It then climbs
soldier1979 [14.2K]

Answer:

-6111.11\ \text{kJ}

863.28\ \text{kJ}

Explanation:

m = Mass of automobile = 1100 kg

v = Velocity of car = 120 km/h = \dfrac{120}{3.6}\ \text{m/s}

h = Height of hill = 80 m

g = Acceleration due to gravity = 9.81\ \text{m/s}^2

Change in kinetic energy

KE=\dfrac{1}{2}m(u^2-v^2)\\\Rightarrow KE=\dfrac{1}{2}\times 1100\times (0-(\dfrac{120}{3.6})^2)\\\Rightarrow KE=-611111.11\ \text{J}

Change in kinetic energy is -6111.11\ \text{kJ}

Change in potential energy is given by

PE=mgh\\\Rightarrow PE=1100\times 9.81\times 80\\\Rightarrow PE=863280\ \text{J}

The change in potential energy is 863.28\ \text{kJ}.
