Answer:
222.5 Gpa
Explanation:
From definition of engineering stress,
where F is applied force and A is original area
Also, engineering strain, where l is original area and is elongation
We also know that Hooke's law states that
Since A=20 mm* 20 mm= 0.02 m*0.02 m
F= 89000 N
l= 100 mm= 0.1 m
By substitution we obtain
Answer:
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.
Explanation:
The last item on the vehicle starting checklist before a driver begins to travel is for the driver to release the service brake.
<h3>What does it mean to release the brake?</h3>
The Release Parking Brake message implies that your parking brake is said to be currently engaged and as such one needs to release the parking brake before one can be able to drive the vehicle.
Therefore, The last item on the vehicle starting checklist before a driver begins to travel is for the driver to release the service brake.

Answer:
vertical load = 10 kN
Modulus of elasticity = 200GPa
Yield stress on the cable = 400 MPa
Safety factor = 2.0
Explanation:
Data
let L =
= 3.35 m
substituting 1.5 m for h and 3 m for the tern (a + b)
= tan⁻¹()
= 45⁰
substituting 1.5 for h and 3 m for (a+ b) yields:
₂ = tan⁻¹ ()
=25.56⁰
checking all the forces, they add up to zero. This means that the system is balanced and there is no resultant force.
