LR = 5m, LG = 2.5m and LC = 1.1m Q2. The Skylark family of sounding rockets consisted of a number of variants (denoted Skylark 5, Skylark 7, and Skylark 12 respectively). These are illustrated on Page 3. The data given below is based on that for the rocket motors they used (all manufactured and named by what was Royal Ordinance – now part of Roxel): Raven XI Motor Total mass: 1280 kg Length = LR See Case Table (units are m) Diameter = 0.44 m Goldfinch IIA Motor Total mass: 420 kg Length = LG See Case Table (units are m) Diameter = 0.44 m Cuckoo IV Motor Total mass: 242 kg Length = LC See Case Table (units are m) Diameter = 0.44 m The payload mass which is additional to the motor masses is to be taken as 100 kg. (a) For the configurations of the three rockets shown on Page 3 in Fig. Q2: (i) Determine the Pitching/Yawing moment of inertia of each rocket about the base of each rocket. (ii) Explain how you could then find the the Pitching/Yawing moment of inertia of each rocket about its…

Elijah Reaper joins the volunteer fire department.  Out practicing his fire hose prowess one day, he attempts to master stabilizing his body while blasting water.  He holds the spray nozzle perfectly horizontal, 2 meters up from the ground, and its diameter is 10 cm.  He finds that his body and strength can only withstand a moment about his feet of 50 Nm to continue holding the hose securely.  What is the maximum volumetric flow of water (m3/sec) that the hose can spray for him to remain standing?

Block 2) A block of mass M slides on a thin film of oil. The film thickness is h and the area of Cord the block A. When released, mass m exerts tension on the cord, causing the block to accelerate. Neglect friction in the pulley and air resistance. Develop an algebraic expression for the viscous force that acts on the block when it moves at speed V. Derive a differential equation for the block speed as a function of time. Obtain an expression for the block speed as function of time. The mass M=5kg, m=lkg, A=25 cm?, and h-0.5 mm. If it takes 1 second for the speed to reach 1 m/s, find oil viscosity u. Oil film (viscosity, u) Mass

Somewhere DEEP BELOW THE EARTH's surface, at an UNKNOWN displacement from the Earth's center, a particle of mass m is dangled from a long string, length L; the particle oscillates along a small arc according to the differential equation d^2x/dt^2=-(pi^2/36)x. Here x refers to an angular displacement measured from the vertical and t refers to time.  The particle's mass is given by m=3kg. The length of the string is given by L=5 meters. Whenever the particle arrives at a location of x=(pi/12) radians from the vertical, the particle has no instantaneous speed. On both sides of the vertical, that is, x=(pi/12) radians is repeatedly observed to be a 'turning point' for the particle's periodic motion. 1. Draw a clear FREE-BODY diagram of this particle at some arbitrary point during oscillation, making sure to label variables and constants described above. 2. Approximating to three significant digits if necessary, what is the angular frequency of this oscillator on a string? 3. Approximating…

An amusement park is designing a new ride. The ride is to have a motorized horizontal launch section that is 5m long. For safety the ride cars will be limited to ⅓g worth of acceleration and will have a typical loaded mass of 400kg. What is the maximum launch velocity of this situation, and what engine power rating is necessary to achieve this velocity?

A hammer head H having a weight of 0.26 lb is moving downwards at 40 ft/s when it strikes the head of a nail of negligible mass and drives it into a block of wood as shown. Find the impulse on the nail if it is assumed that the grip at A is loose, the handle has a negligible mass, and the hammer stays in contact with the nail while it comes to rest.
