Answer:
F = 2,355 10⁵ N
Explanation:
The pressure is distributed throughout the sphere with the same value and is defined by
P = F / A
F = P A
Therefore, on each bolt there is an internal force and external force
∑ F = F_int - F_ext
∑ F = P_int A - P_atm A
F = A (P_int - P_atm)
P_int = 300 10³ + P_atm
F = A 300 10³
The area of the sphere layer is
A = π r² = π/ 4 d²
A = π / 4 1²
A = 0.785 m2
F = 0.785 (300 10³)
F = 2,355 10⁵ N
Hello,
What is the ID Zoom for?
Like what in particular???
The coil polarity in a waste-spark system is determined by the direction in which the coil is wound (left-hand rule for conventional current flow)and can’t be changed. For example, if a V-8 engine has a firing order of 18436572 and the number 1 cylinder is on compression, which cylinder will be on the exhaust stroke?
Answer:
B) 5.05
Explanation:
The wall thickness of a pipe is the difference between the diameter of outer wall and the diameter of inner wall divided by 2. It is given by:
Thickness of pipe = (Outer wall diameter - Inner wall diameter) / 2
Given that:
Inner diameter = ID = 25 ± 0.05, Outer diameter = OD = 35 ± 0.05
Maximum outer diameter = 35 + 0.05 = 35.05
Minimum inner diameter = 25 - 0.05 = 24.95
Thickness of pipe = (maximum outer wall diameter - minimum inner wall diameter) / 2 = (35.05 - 24.95) / 2 = 5.05
or
Thickness = (35 - 25) / 2 + 0.05 = 10/2 + 0.05 = 5 + 0.05 = 5.05
Therefore the LMC wall thickness is 5.05
