Answer:
Explanation:
From the information given:
The total load is distributed across both the rod and tube:
Since this is a composite column; the elongation of both aluminum rod & steel tube is equal.
Replace into equation (1)
Finally, to determine the normal stress in aluminum rod:
Thus, the normal stress = 23.523 MPa in compression.

Answer:
Explanation:
1) First step would be determining the measured force through your experiment for the Reaction force of the both the surfaces on the jet of fluid stream. The value would be R_actual.
2) Second step is to compute the Reaction force by the theoretical model which takes an assumption of no kinetic energy loss from a jet of fluid stream impinging on to the surfaces i.e the velocity before and after impact is the same. This value would be R_theoratical.
3) Step Three would be to compare the actual and theoretical values of Reaction forces exerted by the surfaces by the following formula:
% Difference = [ ( R_actual - R_theoratical ) / R_actual ] * 100
4) The standard followed is that a theoretical model must predicts within 10% uncertainty about the actual value obtained from experiment.
5) If the difference is greater than 10% it means that the assumption of no Kinetic Energy Losses was not feasible and should be included in the model for accuracy.
Answer:
Bulk zoning.
Explanation:
Zoning is a method used by municipal authorities or government authorities to divide a land area into zones. It is a urban planning method. There are several types of zoning; bulk zoning being one of them.
Bulk zoning can be defined as a set of regulations used to control lot size, ratio of floor area, open space, yards, setbacks, bulding height, etc. These setbacks and restrictions, then, help authorities to determine maximun size of a building on a zoning area, and also the positioning of the building.
Therefore, bulk zoning is the correct answer.
