Interpretation:
In a binary phase diagram, it is to be explained as to why commonly only one phase is labelled.
Concept introduction:
Phase diagrams are the geometrical representation of the conditions such as temperature, pressure, composition, etc. of a system at which different phases present in the system exists and are in
These phase diagrams contain phase boundaries which are lines that mark the conditions under which multiple phases can coexist at the equilibrium. Along these lines, the transition of phase occurs.
The point where these phase boundaries intersect are the triple points. At these points, three different phases can exist simultaneously.

- The timber floor framing for a building comprise floor joists using 2" wide nominal lumber is to be constructed as shown in Fig. 1. The Dead load (D) = 26 lbs./ft² (inclusive of joists and flooring) and the live load L= 40 lbs./ft². Lateral torsional buckling is prevented for all members and normal service conditions and temperatures are expected. (i) Design the floor joists using 2" wide nominal lumber using Southern Pine No. 1 (ii) Design the floor beams using Caribbean Pitch Pine (Select Structural). (Assume a 8" x 14” trial section to estimate beam self-weight for your initial design). Density of Caribbean Pitch Pine = 50 lbs/ft³ (800 kN/m³).arrow_forwardConsider the following circuit. + - 1.2 ΚΩ ig (1) vo ΣΕ ΚΩ € 50 nF 200 mH a) [6 pts] The frequency of the source current in the circuit is adjusted until vo is in phase with ig. What is the value of o in radians per second? (Hint: if vo is in phase with ig, the phase of total impedance must be zero (Ztot = vol ig), which means the phase of total admittance is zero. It will be easy to work with admittance in this question because the components are in parallel.) b) [2 pts] What is the total impedance at the frequency found in (a)? c) [2 pts] Ifig=2.5 cosoot mA (where o is the frequency found in [a]), what is the steady-state expression for vo?arrow_forwardP12.38 WP At a point on the free surface of a stressed body, a normal stress of 64 MPa (C) and an unknown positive shear stress exist on a horizontal plane. One principal stress at the point is 8 MPa (C). The absolute maximum shear stress at the point has a magnitude of 95 MPa.

- The ALU for bit 31 shown in the image supported the set on less than (slt) instruction using just the sign bit of Result31. Try this operation on the decimal values a = -7 and b = 6, using a 4-bit, 2's complement representation. Show that this example produces an incorrect value of the Set output. Therefore the Overflow output must also be used to compute Set. Modify ALU31 to handle slt correctly. Show your design on a copy of the figure.arrow_forwardDesign an AC-coupled (input and output) amplifier with a gain of -8 which has identical 3 dB corner frequencies of 10 kHz for high pass coupling at the input and output.

- The attached picture shows the RTCAPI memory mapped register which has the address 0x180. 1) Program the MCU's registers so that a) SIRC is the clock source b) the clock is divided by 16K c) the clock is enabled d) load is enabledarrow_forwardWrite code to generate a PFM signal output to an output pin and then view it via an oscilloscope. The amplitude of the input signal should be changeable by pressing a button and the button presses should be counted via LEDs connected to the microcontroller. Specification: 1. When you start the program, nothing happens and all LED off. 2. When button pressed, use a starting frequency of 1kHz (and LED count 1) 3. With every new button pressed, frequency multiplies by 2 (i.e 2kHz, 4Khz, et.c) and the LED counts accordingly (i.e 2, 3, 4, …,7 and then go back to 0). 4. When the count is 7, it restarts from 0 again (meaning all LEDs are OFF and no signal at the oscilloscope) Recommended Steps: 1. Connect the Switch and the 3 LEDs 2. Connect the limiting resistors to the LED and the pull-up resistor to the switch (The resistor values will be determined in the lab) 3. Write the code to count the button presses (remember to debounce it if necessary) 4. Now generate the Pulses for each count.…arrow_forwardThe device should boot up into the off state, that is, no LEDs are lit. On the depression of a switch on the development board, the first LED color should light and be steady. You you can use any LED colour combinations as you wish. On the depression of a switch a second time, the second LED color should flash with an on time of x msecs where the on duration is specified in the attached PDF and total cycle time of 1 second. The LED should remain flashing until the switch is depressed and the system returns to the off state and return to the start of the state transitions. This should form a cycle: off, steady, and then flashing. In addition, we are going to be storing variables in the EEPROM. You are to write into the EEPROM information so that when the board powers up again, the color of the lights are reversed. Steady should be the second color and flashing should be the first color given to you. Specifically, the 4 programs are as follows:…arrow_forward
