Explanation:
For 787 dreamliner airplane,
Mass, 
Height, 
Potential energy of 787 dreamliner airplane is given by :
For a boeing 747,
Mass, 
Height, 
:
Potential energy of a boeing 747 airplane is given by
So, the potential energy of a boeing 747 airplane is more than the 787 dreamliner airplane.
Answer:
Explanation:
Circle motion
Weight=4lb
Radius=3ft
Velocity Vb= 6ft/s
Velocity Vr=2ft/s
Velocity Vo=12
V2=√Vo²+Vr²
12=√Vo²+2²
Square both side
144=Vo²+4
Vo²=140
Vo=11.83ft/s
Applying conservation of angular momentum
Ha1=Hb2
MbVbr1=MbVor2
r2=Vbr1/Vo
r2=6×3/11.83
r2=1.52ft
The require time is written as.
∆r=Vrt
t=∆r/Vr
t=r1-r2/Vr
t=3-1.52/2
t=0.74sec
Answer:
Bone homeostasis involves multiple but coordinated cellular and molecular events. Two main types of cells are responsible for bone metabolism: osteoblasts (which secrete new bone), and osteoclasts (which break bone down).
Explanation:
According to I.S. standards, the maximum deflection should typically not be greater than 1/325 of the span.
<h3>
What is Beam deflection?</h3>
A beam is a long segment of a body that can support a weight while defying bending. Beam deflection is the term for the movement of a beam when a force is applied to it in a certain direction.
The beam has the ability to be bent or shifted from its initial position. The deflection is represented by this distance along each member point.
The amount of displacement that a certain structural member may experience with the aid of a sizable amount of load is known as deflection. It may also be known as the angle or the separation. The slope of the deflected form of the body under a load directly influences the distance of deflection of a member under that force.
