Answer:
both technician A and Technician B are correct
Explanation:
Technician A says balance shafts are used to counteract vibration created in the engine. Technician B says proper balancing of the engine is important for smooth operation. Which technician is correct
In piston engine engineering, a balance shaft is an eccentric weighted shaft that counteracts vibrations in engine designs that are not inherently balanced. They were first invented and patented by British engineer Frederick W. Lanchester in 1904. ... .The balance shafts have eccentric weights and rotate in opposite direction to each other, which generates a net vertical force. Unavailability of the balance shaft can cause excessive vibration to the engine thereby damaging the oil pump and resulting to engine failure.
Answer:
<em>b) false</em>
Explanation:
The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. Scaling allow us to capture a large geographical area on a reduced platform while still retaining the relative sizes and positioning of places on the map to their real life sizes and positioning. If both maps cover a standard 8.5 by 11-inch sheet of paper, then the map with the smaller ratio will have the bigger geographical area.
To understand better, let us assume two geographical areas A and B. A is bigger than B. If we were to put them both on the same area of map paper, then we'll have to scale up the smaller geographical area B so as to fit into the map paper. This means that the geographical area with the smaller area B will have the larger scale on the map.
