Answer:
Explanation:
From the question we are told that:
Internally pressurized
Tangential Stress
Axial stress
Generally the equation for maximum normal and shear stresses are experienced by the outer surface is mathematically given by
Therefore
Answer:
type 2, k = 4
Explanation:
(a) The transfer function of the controller for a satellite attitude control is
The transfer function of unity feedback structure is
To determine system type for reference tracking, identify the number of poles at origin in the open-loop transfer function.
For unity feedback system, the open-bop transfer function
Determine the poles in G(s)4(s).
s = 0,0,-5
Type of he system is decided by the number of poles at origin in the open loop transfer function.
Since, there are two poles at origin, the type of the system will be 2.
Therefore, the system type is
Type 2

Karl Benz built his first automobile in 1885 in Mannheim.
Answer:
A total = 0.04 m²
Explanation:
given data
mass = 75 kg
area = 0.05 m²
pressure = 3 kPa
solution
pressure when human walking on ground
p = .................1
p =
p = 14.715 kPa
and
when walk on snow got extra pressure
P total = p + p (extra) ................2
P total = 14.715 + 3 = 17.715 kPa
and
total pressure is also
p total =
A total =
A total = 0.04 m²
Answer:
Hydraulics is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases.
