Answer:
t = 5.55 mm
Explanation:
given,
Gauge pressure (P)=640 kpa
Allowable normal stress =150 Mpa.
Inner diameter of tank =2.6 m.
Minimum thickness of wall. = ?
In case of closed cylinders there are two cases.
one is Circumferential stress and another one is longitudinal stress.
According to circumferential stress
Where
p=pressure, d=diameter, t= thickness,
by substituting all values we get,
t = 5.55 mm
minimum thickness of the wall is equal to t = 5.55 mm
Answer:
the period T of whole motion should be twice the value for half at he bottom so T is 0.2sec.
w is angular frequency
formula:2π/T
now k is spring constant
F/R-->mw²
putting values:70*(2π/0.2)²
=4.9x10⁶
so we can say that SHM is not affected by the amplitude of the bounce.
the answer would be white body
momentum= mass × velocity = 0.141kg×1.33m/s= 0.18753kg m/s = 0.188kg m/s (3s.f.)
Answer:
Explanation:
Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.
The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:
Substitute the values into the formula.
Multiply.
- 1 kilogram meter per square second is equal to 1 Newton.
- Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.
The force required is <u>252.5 Newtons</u>.
