...Laws. Here, you need the Second Law which relates force (F), mass (m) and acceleration (a) as shown in Equation 1. cap f equals m times a Equation label: Equation 1 You need to change the mass of the rocket – in this case, say 40 tonnes – into kg. So, the mass m = 40 × 1000 kg = 40 000 kg = 4 × 104 kg. Question 4 in Activity 5 provided an approximate value of the...

...law). However, the rate of the satellite's axial spin remains constant. Thus although for every orbit completed the satellite rotates exactly once, during the closest part of its orbit its rotation lags slightly behind its orbital motion, and during the furthest part of its orbit its rotation is slightly ahead of its orbital motion. Consequently, as seen from the planet,...

...law of hydrostatics cap p sub atm equals rho times g times h so equation sequence part 1 h equals part 2 cap p sub atm divided by rho times g equals part 3 101.325 multiplication 10 cubed Pa divided by 1.225 kg m super negative three multiplication 9.81 m s super negative two equals part 4 8431.6 times ellipsis m full stop Therefore the height of the atmosphere would be...

...law and strain/stress (constitutive) relations. The major stages in the creation of any finite element model, according to Baguley and Hose (1997), for most types of analysis are: selection of analysis type idealisation of material properties creation of model geometry application of supports or constraints application of loads solution optimisation. It is extremely...
