. A hollow cast-iron cylinder 4m long, 300mm outer diameter, and thickness of metal 50mm is subjected to a central load on the top when standing straight. The stress produced is 75000kN/m2. Assume Young's modulus for cast iron as 1.5x 108 kN/m^2 and find (i) magnitude of the load, (ii) longitudinal strain produced, and (iii) total decrease in length

A small memory system for the 8086 microprocessor contains an EPROM section and a RAM section

Design a conductor which is part of large circuit, such that
when it is placed in XY plane it produces a magnetic field of
magnitude 100 mA/meter at point (0, 0, 10). You may assume
that one end of conductor from where the current starts is
placed at origin and leads to the other end of conductor at
point (x, y) which needs to be determined to design the
conductor. The current in conductor must not exceed 10
Ampere.

You are designing the windows of an aeroplane. Would you design them as squares, ovals or hexagons? Justify your answer

1.The open loop transfer function or a unity feedback system is given by:
G(s)=K/s(1+sT)
where,K ans T are constants.by what the factor of amplifire gain ne reduce to that peak overshoot ,of unit step response of system is reduce from 75% to 25%.

The amplifier TL084 Pin connections.(multisim view.as shown in Fig... U2A 1 TL084CN Fig 1. TL084 Pin connections (multisim view) Design 1(50%) 1) Please use TL084 to design a non-inverting amplifier (In a non-inverting amplifier, the output voltage changes in an same direction to the input voltage.) The voltage amplification factor is 6 in you design circuits. (Write design process).(20') 2) Implementation the circuits in the multisim and measure Uipp Uopp using oscilloscope and show your multisim results to the teacher. The Vin-pp=200mV, f=1KHz. (20%) 3.) Draw the input and output waveforms of you circuits, and mark the relevant parameters. (10)

Imagine you are in a college campus where all the students stay in a hostel. There is a
scenario where the older students want to give away, rent or sell their belongings like
musical instruments, Bicycle, electronic gadgets etc. and the junior students want to buy
or take it from them
