Question: During an engine test on the ground, a propeller thrust T=3000 N is generated on the 1800-kg airplane with mass center at G (the weight of the airplane acts at this point). The main wheels at B are locked and do not skid (i.e. there will also be a reaction in the X-direction at this support); the small tail wheel at A (only one wheel) has no brake.
1) The reactions at the supports are: RA= ? RBx=? RBy=?
2) Considering the engine to be off (T=0), the reactions at the supports are: RA=? RBx=? RBy=?
An 8.70-kg block slides with an initial speed of 1.80 m/s down a ramp inclined at an angle of 22.2 deg with the horizontal. Use energy conservation to find the distance the block slides before coming to rest
A 0.35kg mass suspended from a spring moves with simple harmonic motion. At the instant mass is displaced from equilibrium by -0.105 m, what is its acceleration? (The spring constant is 11.8N/m)
The waveform is an exponential current whose direction of flow reverses after 4 ms and terminates after 8 ms. Write an expression for this waveform using the basic signals discussed.

A nuclear power plant generates 3000 MW of energy from nuclear reactions in reactor’s core. This energy is used to boil water and produce high pressure steam at 300 0C.
Use Ampere’s law to determine the magnetic field in a densely wound toroidal solenoid with inner radius a, outer radius b, and N total turns. The cross section of the solenoid is a rectangle of width b-a and height h.

An elastic cord is 69.3 centimeter long when a weight of 70.2 Newton hangs from it but is 87.1 centimeter long when a weight of 184 Newton hangs from it. Obtain the spring constant of this elastic cord
The intensity of radiation from a distant source like the Sunvaries inversely with the square of the distance from thesource. At the top of Earth's atmosphere the solar intensity(power per unit area) is 1.35 kW/m2.
How long after the beginning of the power failure would it have taken the flywheel to stop if the power had not come back on? Explain how many revolutions would the wheel have made during this time?
