The reverse water-gas reaction is an undesirable side-reaction during industrial hydrogen production:
CO2 + H2 ↔ CO + H2O
(A)What is the equilibrium composition of a mixture at 1500K that initially contained 40 mol. % CO2,
30 mol. % H2, 20 mol. % CO and 10 mol. % H2O? Employ canonical partition functions.
(B) Employ the JANAF table data to find this mixture composition at equilibrium at 1500K and
compare it to the results in part (A). Do they agree? How can one explain the differences?

What is the goal of pushover analysis in the structure and why we need to perform it?

What are the methodology and framework that can be use in seismic evaluation using modal pushover analysis?

To push a 25 kg crate up a 27° inclined plane, a worker exerts a force of 120 N, parallel to the incline. As the crate slides 3.6 m, how much is the work done by the worker and by the force of gravity?

A large coil spring with a spring constant k = 120 N/m is elongated, within its elastic range by 1 m. Compute the store energy of the spring in N-m.

A 50 kg object strikes the unstretched spring to a vertical wall having a spring constant of 20 kN/m. Find the maximum deflection of the spring. The velocity of the object before it strikes the spring is 40 m/s.

A block weighing 500 N is dropped from a height of 1.2 m upon a spring whose modulus is 20 n/mm. What velocity will the block have at the instant the spring is deformed 100 mm?

A 200 N weight falls from rest at height “h” and strikes spring having a spring constant of 10 N/mm. the maximum compression of spring is 100 mm, after the weight the weight strikes the spring. Compute the value of h is meter.

A 100 N weight falls from rest from a height of 500 mm and strikes a spring which compresses by 100 mm. Compute the value of the spring constant, neglecting the mass of the spring.

A body that weighs W Newton fall from rest from a height 600 mm and strikes a spring whose scale is 7 N/mm. If the maximum compression of the spring is 150 mm, what is the value of W? Disregard the mass of spring.

A small rocket propelled test vehicle with a total mass of 100 kg starts from rest at A and moves with negligible friction along the track in the vertical plane as shown. If the propelling rocket exerts a constant thrust T of 1.5 kN from A to position B. where it is shut off, determine the distance S that the vehicle rolls up the incline before stopping. The loss of mass due to the expulsion of gases by the rocket is small and may be neglected.
