Find attached of the diagram that complete the question.
Velocity = 1.5 sec²θ m/s
Acceleration = 9 sec²θtanθ m/s²
Explanation:
Calculating the velocity:
V = dx/dt
x = 0.5tanθ
θ = 3t
ö = 3
V = d(0.5tanθ)/dt
= 0.5*sec²θ*ö
= 3*0.5sec²θ
= 1.5 sec²θ m/s
Calculating the acceleration, we have;
a = dv/dt
= d(1.5sec²θ)/dt
= 1.5*2sec²θtanθ*ö
= 1.5*2sec²θtanθ*3
= 9sec²θtanθ m/s²
Answer:
The diameter of the test cylinder should be 7.65 meters.
Explanation:
The Hooke's law relation between stress and strain is mathematically represented as
Where 'E' is modulus of elasticity of the material
Now by definition of strain we have
Applying values to obtain strain we get
Thus the stress developed in the material equals
Now by definition of stress we have
Solving for 'D' we get
