TASK 3
Task 3 requires you to carry out a full risk assessment on a typical item or area from your selected working environment with which you are familiar with. You need to include all the hazards identified in task 2 and also use the Health and Safety `five steps to risk assessment’ procedures to complete this task.
Task4
A) This task requires you to suggest suitable control measures for the risks identified in your risk assessment in task 3 and state the reasons why they are suitable.
B) For each of the control measures identified in Task 4a describe how the control measures can prevent accidents.
Describe the methods used to identify the health and safety hazards that may be present in the working environment with which you are familiar.
Photographic evidence is required to show the hazards identified.
You need to identify the waste materials generated from your selected working environment and explain the requirements for the safe disposal of these waste materials.

Explain the Memory stack organization of 16 locations of stack( 0 to 15). take the initial value of the
stack pointer is SP = 0E in Hex. Explain the following push and pop instructions through the Memory
stack organization diagram.
(1) PUSH R5 WHERE R5 = XX in Hex
(2) POP R4 WHERE R4 = (XX + 3 ) Hex for example roll no 64 is having the data in R5 = 64
Hex and R4 is ( 64+3 = 67 Hex)
The unique addresses assigned to the four registers (R11,R12,13,R14) of the I/O interface are equal
to the 373 , 377 , 37B and 37F in Hex . Where XX is hex digits equal to your roll no . (if student is having
roll no 45 than address are 453 ,457 ,45B , 45F in Hex ) .Show the well labeled external circuit that must
be connected between and 12-bit I/O address from the CPU and the CS, RSI, and RS0 Inputs of the
Interfaces

The open loop transfer function {Please note: open loop TF is the forward TF times the feedback TF i.e., 𝐺(𝑠)𝐻(𝑠)} of a unity feedback control system is given by 𝐺(𝑠) = 25 𝑠(𝑠+5) . a. Calculate the natural frequency of oscillation, the damped frequency of oscillations, damping ratio, the exponential frequency, percentage overshoot for a unit step input. b. The non-zero and finite steady state error for the appropriate input depending on the system type. c. If the damping ratio is to be made to 0.75 from the original value obtained in 2 (a) using a tachometer feedback, calculate the tachometer constant 𝐾𝑡 and determine the percentage overshoot then
