Cathy, a 125lb actress playing Peter Pan, is hoisted above the stage in order to “fly” by a stagehand pulling on a compound pulley system that has 6 supporting strands with a force of 30lbs. A) What is the ideal mechanical advantage of the pulley?
Answer:
The ideal mechanical advantage (IMA) of the pulley is 6
Explanation:
The question parameters are;
The mass of the actress playing Peter Pan = 125 lb
The force applied by the stagehand to the pulley to hoist her = 30 lbs
The Ideal Mechanical Advantage (IMA) of a pulley = The number of strands (rope) the pulley has
Therefore, the Ideal Mechanical Advantage (IMA) of the given pulley with 6 strands = 6.

Technician A says power steering pumps can be engine driven. Technician B says power steering
pumps can be electrically driven. Who is correct?
Select one:
A. Technician A
B. Technician B
C. Both A and B
D. Neither Anor B
Answer:
The correct option is;
C. Both A and B
Explanation:
Power steering supplies power more steering power when a driver turns the wheel to leverage the input steering effort of the driver thereby providing more steering with small effort
The power steering pumps which supply the power that to the fluid that eases steering of the wheel can be driven by the engine through a belt and pulley system or it can be installed in the front of the vehicle and from there, electrically driven alongside the refrigerant compressor
Therefore, both Technician A and Technician B are correct
What is the shortest distance from the root of a fillet weld to its face?
1. What's the maximum overall length of the part?
2. What material is used to fabricate the part
Answer:
1. The maximum length overall length of the part is 4 inches
2. The material with which the part is fabricated is 0.25 inch thick Hot Rolled Steel
Explanation:
The information given in the drawing are;
The angle of projection of the drawing = Third angle projection
The thickness of the material = 0.25" plate
The material with which the part is fabricated = 0.25 inch thick HRS
HRS is the acronym for Hot Rolled Steel
Therefore;
The material with which the part is fabricated is 0.25 inch thick Hot Rolled Steel
The scale of the drawing = 1:1 = which is 1 is to 1 drawing
The maximum length overall length of the part, l = 4 units
By visually testing the 1:1 scale drawing measurements of 4 units is comparable 4 inches measurement with an online ruler
Therefore;
The maximum length overall length of the part, l = 4 inches
