Microprocessor: Assume, a switch is connected to bit 0 (LSB) of the input port (address $9000). If that bit is one (1), the switch is ON. A light bulb is connected to bit 7 (MSB) of out port (address $8000). A one (1) makes the bulb ON. If the switch is ON, we are going to make the bulb ON otherwise keep it OFF. Write an input/output program to control the light bulb.

What precautions should you take to prevent injuries when dealing with heavy loads?

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
