An engineering consulting firm measures its output in a standard service hour unit, which
is a function of the personnel grade levels in the professional staff. The variable cost is
$62 per standard service hour. The charge-out rate (i.e., selling price) is $85.56 per hour.
The maximum output of the firm is 160,000 hours per year, and its fixed cost is
$2,024,000 per year. What is the breakeven point in standard service hours and in
percentage of total capacity?

A loan of $10,000 is to be repaid over a period of eight years. During the first four years, exactly half of the loan principal is to be repaid (along with accumulated compound interest) by a uniform series of payments of A1 dollar per year. The other half of the loan principal is to be repaid over four years, with accumulated interest, by a uniform series of payments of A2 dollar per year, If i=9% per year, what are A1 and A2?

Testing servo motor with arduino

Testing servo motor with arduino Components Needed: Arduino board (e.g., Arduino Uno) Servo motor Jumper wires Steps for Connection: Servo Motor Pins: Ground (GND): Usually the brown or black wire of the servo motor. Power (VCC): Usually the red wire of the servo motor. Control Signal (PWM): Usually the yellow, orange, or white wire of the servo motor. Connecting to Arduino: Ground (GND): Connect the ground wire of the servo motor to one of the GND pins on the Arduino. Power (VCC): Connect the power wire of the servo motor to the 5V pin on the Arduino. Control Signal (PWM): Connect the control signal wire of the servo motor to digital pin 9 on the Arduino, as specified in the code by myservo.attach(9); Connection Arduino Servo motor VCC/ 5V Red wire GND Black Wire 9 Yellow wire Explanation: Ground (GND): This connection ensures that the servo motor and the Arduino share a common ground, which is necessary for proper operation. Power (VCC): The servo motor needs a power supply t

CanSat

CanSat is a type of small satellite that is designed to fit inside a soda can. These miniature satellites are used for a variety of purposes, including educational projects, scientific research, and commercial applications. The CanSat concept was first developed in 1998 by Bob Twiggs, a professor at Stanford University, and Jordi Puig-Suari, a professor at California Polytechnic State University. They wanted to create a low-cost, hands-on way for students to learn about satellite technology and space science. Since then, CanSats have become a popular platform for educational projects around the world. They are often used in STEM (Science, Technology, Engineering, and Mathematics) education programs, where students are tasked with designing, building, and launching their own CanSats. A typical CanSat consists of a soda can-sized container that houses a variety of sensors, such as temperature, humidity, pressure, and acceleration sensors. It also includes a small computer, a radio tran
