Answer:
The main disadvantage of the Bezier-curves is the global influence of the control points on the whole curve.
This has two major drawbacks: (1) every change of a control point (insert, move, delete) changes the look of the curve in all points of the curve, and (2) the computation time needed for a big set of control points is comparatively high. The reason is the weighting-function form.

Answer:
The correct option is d ( Neither A nor B)
Explanation:
Technician A made 2 mistakes in his statement.Firstly the tire is self supporting not self sealing.
Secondly, this tire does not provide permanent sealing of punctured area option a is incorrect.
This self-supporting tire after being affected with complete air leakage can temporarily bear the load of the car and avoid rolling over a distance of 80 km at a maximum speed of 55 mph. Here is what technician B suggested incorrectly as the tire after being.Here the technician B suggested incorrectly as the tire after being affected with puncture can not travel at any speed so option B is wrong
Since option a and b are incorrect and c is invalid.
Answer:
True strain = 3.7704
Explanation:
Strain is the measure an object that is stretched or deformed. This occurs when a force is applied to an object. Strain deals mostly with the change in length of the object. Strain = Δ L /L = Change in Length over the original Length:
Volume Constancy :
ΔL/L0=A0/ΔA=(D0/ ΔD)=(25mm/0.75mm)^2
ΔL/L0=44.4
Engineering strain:
Engineering strain =ΔL-L0/L0=ΔL/L0-1
Engineering strain =44.4-1=43.4
True strain, ε=In(ΔL/L0)=In(43.4)=3.7704
Note that strain has no unit, so the True strain = 3.7704
