Answer:
C.30°
Explanation:
Given that compound swivel base is set on 60° at the lathe center line index.
We need to find reading on cross slide index
We know that relationship between center line index and cross slide index in angle 2∝=β
Where ∝ Angle of swivel and β is the reading on cross line index.
So by using above relationship between center line index and cross slide index
2∝=60°⇒∝=30°
So our option is C.
Explanation:
The following evidence could be used by an engineer;
The study of areodynamics and the fact that there are four parameters lift, weight, thrust and drag can explain the flying of airplanes in sky
Lift is a force that pushes the plane to rise ad it is actually the design of wings and their movements that create this lifting force
Weight is the force necessary to consider to make the plane fly and land
Then comes thrust, developed via engines or propellers of an airplane.
Last force is drag which defines the force needed to keep the plane pass through air.
A well calculated combination of all four forces actually make a plan fly
Answer:
It serves as a guarantee that the contractor who wins the bid will honor the terms of the bid after the contract is signed.
Explanation:
A bid bond is a type of construction bond that protects the obligee in a construction bidding process.
A bid bond typically involves three parties:
The obligee; the owner or developer of the construction project under bid. The principal; the bidder or proposed contractor.
The surety; the agency that issues the bid bond to the principal example insurance company or bank.
A bid bond generally serves as a guarantee that the contractor who wins the bid will honor the terms of the bid after the contract is signed.
6 feet
Explanation: A few extra feet of free fall can significantly increase the arresting force on the employee, possibly to the point of causing injury. Because of this, the free fall distance should be kept at a minimum, and, as required by the standard, in no case greater than 6 feet (1.8 m).
