What is the total change in velocity required to go from a 200 km altitude circular, Earth orbit to circular orbit with a radius of 384,000 km (the mean radius of moons orbit relative to the earth, but ignore the moons presence}?
a uniform rectangular cabinet having dimensions shown and mass m=50kg is placed onto a cart of mass 10 kg as shown. no slipping between cabinet and cart. determine the maximum allowable force P so that the cabinet does not tip.
explain in your own words what standard deviation is and why it is useful when describing experimental data. 2. what

A lap joint needs to be designed using 20-mm diameter bolts to carry a load of 120 kN on the connecting plates. If the shear stress in each rivet is not to exceed 90 MPa, determine the number of bolts needed.
a w200 x 31.3 rolled-steel beam is subjected to a couple m of moment 45 kn.m. knowing that e 200 gpa and v 0.29
The only force acting on an earth satellite traveling outside of the earth’s atmosphere is the radial gravitational attraction. The moment of this force is zero about the earth’s center taken as a fixed point. Prove that r2? Remains constant for the ..
When the average grain diameter is increased to 3.20x10-2 mm, what is the modulus of resilience (in J/m^3) if the modulus of elasticity is known to be 134 GPa?
A uniform bar of length l and weight w is suspended symmetrically by two strings, set up the differential equation of motion for small angular oscillations of the bar about the vertical axis, and determine its period.
consider an isentropic expansion process in a piston cylinder device where air is expanded from 1mpa and 800 k to 0.1
A rigid container of 0.1 m3 and negligible heat capacity contains steam at 500 kPa and 400C. If the container is cooled, determine the pressure and temperature at which steam starts to condense. Determine also the amount of heat removed during the co..
