By converting the sum of minterms in problem 6 to product of appropriate maxterms, find the POS expression, simplify that using Boolean algebra, and find the NOR-only circuit?

This is problem 6 which I already answered: Design the simplest circuit that implements the function f(x1,x2,x3)=m(3,4,6,7) using NAND gates. (For problem 6, first find the SOP, then simplify that using Boolean Algebra, then draw a NAND-only circuit)

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.
