Royce has a Bevel protractor with a damaged vernier scale. What limitation will Royce face if he uses this protractor to measure angles?
Answer:
Limitation in the level of possible accuracy of the that can be obtained to mainly whole degrees
Explanation:
The angle measurement values are located around the circularly shaped bevel protractor to which a Vernier scale can be attached to increase the accuracy of the angle measurement reading
The accuracy of the bevel protractor is up to 5 arc minutes or 1/12° with the space on the Vernier scale having graduations of 1/12°, such that two spaces on the main scale is 5 arc minutes more than a space on the Vernier scale and the dimensions of the coincidence of the two scale will have an accuracy of up to 1/12°
Therefore, whereby the Vernier scale is damaged, the accuracy will be limited to the accuracy main scale reading in whole degrees.

QUESTION 1: Different Line Types Look at the drawing of a different bicycle pump below. This drawing is accurate, so we call it a scale draw It is four times smaller than a real pump. We say it is drawn to a scale of 1:4. That means that if you meas the length of the outer tube of this drawing, it will be four times smaller than the outer tube of the real pu F + 320 Figure 9: Bicycle pump. Scale 1:4 Why is the outer tube of this pump drawn with solid lines?
Answer:
The outer tube of the pump is drawn with solid lines because it represents the visible edges of the object, which are the most important and prominent features of the drawing. Solid lines are used to indicate visible edges, while other types of lines such as dashed or dotted lines are used for hidden or construction lines that are not meant to be seen in the final drawing.
Explanation:
When drawing an object, it's important to distinguish between the visible edges and the hidden or construction lines. The visible edges are the lines that represent the outer contour or silhouette of the object, which define its shape and form. In the case of the bicycle pump, the outer tube is the most prominent and recognizable feature of the pump, so it's drawn with solid lines to emphasize its importance and to make it stand out from the other parts of the pump.
On the other hand, the hidden or construction lines are used to guide the drawing process, to show the internal structure or components of the object, or to indicate the position of other features that are not visible from the current viewpoint. These lines are usually drawn with dashed or dotted lines to distinguish them from the visible edges and to avoid confusion.
By using different types of lines, the artist can create a clear and accurate representation of the object, with all the relevant information conveyed in a concise and understandable way. This is especially important in technical or scientific drawings, where precision and clarity are essential for conveying complex ideas or designs.

The connecting rod is attached to the piston using a wrist pin. (Option B)
How is this so?The wrist pin,also known as a piston pin or gudgeon pin, serves as the pivot point between the connecting rod and the piston.
It is inserted into small bores in the piston and connected to the big end of the connecting rod,allowing the piston to move up and down while maintaining a secure connection to the connecting rod.
The con-rod connects the piston to the crankshaft, allowing combustion pressure to be transferredto the crankpin.

Explanation:
A water turbine is to be designed to produce 27MW when running at 93.7 rev/min
under a head of 16.5m. A model turbine with an output of 37.5kW is tested under
dynamically similar conditions with a head of 4.9m . Calculate the:
a. model speed; b. scale ratio; c. assuming a model efficiency of 88%, estimate the volume
flow rate through the model; and d. if it is estimated that the force on the thrust bearing of
the full-size machine is 7.0GN , determine the bearing thrust of the model.
The Answers for the given question are as follow:
a. The model speed is approximately 31.62 rev/min.
b. The scale ratio is approximately 0.0417.
c. The estimated volume flow rate through the model is approximately 943.44 m^3/s.
d. The bearing thrust of the model is approximately 9.72 kN.
To calculate the required values for the water turbine model, we can utilize the concept of dynamic similarity.
a. To find the model speed, we can use the principle of geometric similarity, which states that the ratio of speeds is equal to the ratio of the square roots of the head. Thus:
Model speed = (√(Model head))/(√(Full-size head)) * Full-size speed
= (√4.9/√16.5) * 93.7 rev/min
= 31.62 rev/min
b. The scale ratio can be determined using the equation:
Scale ratio = (√(Model power))/(√(Full-size power))
= (√37.5kW)/(√27MW)
≈ 0.0417
c. To estimate the volume flow rate through the model, we can use the power equation:
Model power = (Model efficiency) * (Volume flow rate) * (Model head) * (Gravity)
37.5kW = 0.88 * (Volume flow rate) * 4.9m * (9.81m/s^2)
Solving for the volume flow rate:
Volume flow rate = 37.5kW / (0.88 * 4.9m * 9.81m/s^2)
≈ 943.44 m^3/s
d. To calculate the bearing thrust of the model, we can use the principle of force similarity:
Bearing thrust model = (Model power / Full-size power) * Full-size bearing thrust
= (37.5kW / 27MW) * 7.0GN
≈ 9.72kN

For a thrust of 130,000 N and a thrust time of 100 S, what is the rockets mass that makes the rocket reach 220 KM
The rocket mass that would make a rocket with a thrust of 130,000 N reach 220 Km would be 2,954.55 kg.
How to find the rocket mass ?To solve this problem, we need to apply the basic equations of motion. We will assume that the only force acting on the rocket is the thrust force, and we will ignore the effects of air resistance and gravity.
Calculate acceleration (a) using thrust (F) and mass (m):
Given the thrust F = 130,000 N, we have:
a = 130,000 / m
Apply the equation of motion:
Given y = 220,000 m (220 km), y0 = 0 m (initial position), v0 = 0 m/s (initial velocity), and t = 100 s, we can write the equation as:
220,000 = 0 + 0 * 100 + 0.5 * (130,000 / m) * (100)^2
Solve for mass (m):
220,000 = 0.5 * (130,000 / m) * 10,000
440,000 = 130,000 * 10,000 / m
m = 130,000 * 10,000 / 440,000
m = 2, 954.55 kg
In conclusion, the mass of the rocket that makes it reach 220 km with a thrust of 130,000 N and a thrust time of 100 s is approximately 2, 954.55 kg.
