Chapter 2.2, Problem 2R
What is the size of the footing for the steel Lally columns in the basement? Refer to Plan 1 of 10. (Lally is the trademark used for a concrete-filled steel cylinder used as a supporting member for wood or steel girders and beams. The Lally column was named after John Lally, born in Ireland in 1859. The term lolly is also used.) __________

Q3:
Material A and Material B are collected in a tank as
shown where the system consists of three Push-Button,
three Level Sensors, two Inlet valve, one Outlet valve,
Heater, Temperature Sensor, Agitator Motor, and
Alarm Light. Material A and Material B are to be
mixed and heated until it reaches 90°C temperature,
and it will be drain using outlet valve also high-level
Alarm Light will come ON when the tank is full and
stay on even if the tank level drops until the operator
press Reset Push-Button. Implement automation of
this system in PLC using Ladder Diagram
programming language (Note: The tank is fed with
Material A before B and the temperature sensor can
withstand 200°C and it gives voltage from 0 to 10
volts)
