Answer:
Attached is the logic diagram.
Explanation:
Motion Sensors S1 S1 S3 S4
Master switch M
Siren Enable Switch A
Light Enable Switch L
Phone Call Enable Switch P
Buzzing Siren B
Flashing Light F
Call Box C
The logic operates as follows, when ANY of the sensors goes active (1), the output must be active, so for the sensors inputs we use an OR gate. After that the OR signal output goes to the switches AND gates, if any of the switches is off, the outputs are going to be LOW or (0)

Kilometer = 1000m
Quart = 0.000946m³
Force = mass × acceleration
=> F = ma
Putting units:
Newton = kg.m/s² or kg.m.s^-2 _____(1)
Pressure = force/area
Putting units:
Pascal = Newton/m²
=> Pascal = kg.m.s^-2.m² [from (1)]
=> Pascal = kg.m^-1.s^-2
Work = force × displacement
=> W = Fs
Putting units:
Joule = Newton.m
=> Joule = kg.m.s^-2.m [from (1)]
=> Joule = kg.m².s^-2 ______(2)
Power = work/time
Putting units:
Watt = joule/s
=> Watt = kg.m².s^-2/s [from (2)]
=> Watt = kg.m².s^-3 ______(3)
Horsepower = 746 watt
=> Horsepower = 746kg.m².s^-3 [from (3)]

Answer:
Explanation:
a) On the verge of tipping over, reaction acts at the corner A
When slippage occurs,
Block moves w/ const. velocity equilibrium
Three-force member: reaction at A must pass through B
tan b/2h, h b/ 2 θ µ = = ∴= k k ( µ )
b) When slippage occurs,
Block moves w/ const. velocity equilibrium
Three-force member: reaction at C must pass through G
k tanθ µ =
tan x/ H/2 , x H/2
