Question 16 Calculate Ixx and lyy at the centroidal axis. First, the disc shape: 164 cm^4 O 104 cm 4 O 104 m^4 O none are correct 1 pts
Question 14 What is the location of the centroid in the z direction? O 30 cm from the bottom 9.73 cm from the bettemt 25.7 cm from thetop O last two are correct 5 pts
Question 12 5 pts What is the mass of the remaining section multiplied by its centroid (of reference)? This rendering represents a nozzle for a rocket. The top of nozzle is made from titanium whose density is 8 kg/m^3. This piece can be considered a disc with a height of 5 cm and a diameter of 10 cm. There is a hollow core within this disc whose radius is 2 cm. The next section underneath the top is known as a throat. This piece is made from a high grade steel whose density is 10 kg/m^3. The nozzle is essentially a square tube with a 1 cm wall thickness and a side measuring 4 cm. The final cone shape is a solid hemisphere (paraboliod) made from a composite with a density of 5 kg/m^3. The height of the hemisphere is 26 cm and the diameter is 40 cm. The formula for the centroid of a paraboliod is h/3 and its volume can be approximated by 1/2pi*r^2(h). 0646-kg-om 568 kg cm O 1.845 kg cm O.0845 kg cm
