a. Calculate the synchronous speed of a
3-phase, 12-pole induction motor that is
excited by a 60 Hz source.
b. What is the nominal speed if the slip at
full-load is 6 percent?
A 3-phase, 75 hp, 440 V induction motor
has a full-load efficiency of 91 percent and
a power factor of 83 percent. Calculate the
nominal current per phase.
Please answer all the questions
a) What is the minimum required transformer rating for each transformer in kVA? b) Find the voltage required at Bus 1. c) The loadcentre is to be powered by PV panels that have the same I-V curve (ISC = 120 A, VOC = 60 V). Identify the configuration that uses the minimum number of panels to provide enough power to Bus 1. You can assume that the inverter converts the power at 95% efficiency and requires V DC input to generate the same VRMS AC output.

The pin acts as a moment release, i.e. no moments are transferred through this pinned connection. Shear forces can be transferred through the pinned connection. Beam ABC has a pinned support at point A and a roller support at Point C. Beam CD has a roller support at Point D. A concentrated load, P, is applied to the mid span of beam CD, and acts at an angle as shown below. Two concentrated moments, MB and Mc act in the directions shown at Point B and Point C respectively. The magnitude of these moments is PL.

Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1.
