Wind turbine blades are airfoil-shaped blades that use wind energy to propel a wind turbine's rotor. In a fixed-wing aircraft, the airfoil-shaped design creates lift by allowing the blades to exert lift perpendicular to the wind direction. Recommend a material for this sort of turbine blade and explain your choice.
(6) There are many kinds of polyethylene foam, each with different properties.
The low density polyethylene foams (as seen
in this video) are very flexible.
Remember: in solid mechanics, "flexible"
just means that in comparison to other
materials, the material deforms quite a
bit, relative to the stress.
For torsion, the material property that relates
to stiffness is the shear modulus (or modulus
of rigidity), G. We'll say that G = 6 MPa.
a) Complete the FBD.
b) Compute the shear stress at Point B.
c) Illustrate it on a stress element.
d) Report the shear strain at B (in radians).
e) Compute the rotation of the top plane.
f) Compute arc length s.

- As an automobile accessory designer, you must choose between two materials for building bulletproof windows. You put each substance to the test by shooting one bullet at it.

Argue on which is the best material to use to make the windows bulletproof.arrow_forwardYou are looking for properties of a new lubricant your company uses, but only have access to a manual that is written in a foreign language, so you can't read the headers of a table with the material properties. However, the units are all in standard SI symbols. Which quantity is (most likely) the surface tension? The one with units of m2/s The one with units of N/m The one with units of N-s/m2 The one that is m2/(s²"K) The one with units of kg/m3 QUESTION 4 A large helium balloon, which can be approximated as a cylinder with a length of 5 m and a diameter of 2 m, is moored in standard atmospheric air via a small rope. What is the tensile force on the cord? Consider helium's density to be 0.17 kg/m3 and neglect the weight of the rope and thin material that makes the balloon's walls. 16.2 N 637 N 26.2 N 79.7 N 159 Narrow_forwardWhen lifting weights, it turns out the amount of force you need to lift them doesn't necessarily match the dumbbell's weight — in other words, if an object weighs 100 N, the amount of force you actually need to apply is probably not 100 N. Observe the diagram below: You can think of the bones in your arms as rods that rotate about an axis of rotation (your elbow) depending on the magnitude, direction and position of the forces being applied. So in order for your arm to lift the weight, the torque exerted by the bicep should be greater than or equal to the torques being applied by the bones' center of mass and the weight your hand is holding. Notice how the bicep is connected to the arm bone (the radius) at a certain distance from the joint, and applies an upwards tension force (as the bicep contracts in order to lift objects). Show how the magnitude of the tension force exerted by the biceps muscle can differ greatly from the magnitude of the weight.arrow_forward
