The Aristurtle team is on a winter vacation in the Alps. Twenty brave members decide to take the aerial tramway ride. The cabin of a aerial tramway can carry up to 20 people with a total mass of 2021 kg. The cabin rises at a constant speed from the base of the mountain at 2022m to the top at 3650m.
Use g=9.80
a) How much work is produced by the engine to move the cab up the mountain? (Answer in MJ, one decimal)
b) How much work does the force of gravity in the cabin produce?
(Answer in MJ, one decimal)
c) If the engine can produce 18% more work than it does in case a, what will be the acceleration of the cab? (Two decimals)

There was a water cut in Sindos. A manufacturer urgently wanted to use water to complete some processes for Aristurtle's sixth car. So, he used his tank, with the help of a pump.
Please, write the power provided in the pump when the performance is 55% .
Also, g= 9.80 , pipe length=50m , pipe is smooth.
Find the value of moment at these points :
i) A , B , C , D and at the point in the middle of the BC section.
ii) Half meter left to force P, find the value of shear force and half meter right to force P find the value of axial force.
The big-bottle full of water at Oikiskos A has a mass of 3.23 kg and when it is empty it has a mass of 250g .
An Aristurtle member filled the bottle with a liquid he found in Oikiskos B. And the bottle weighed 2.22 kg What is the specific gravity of the liquid from Oikiskos B?
Please give the asnwer with 3 decimals

The Aristurtle team has a meeting at the BMW headquarters which is located in a
12-floor (10ft each floor) building in Munich. The meeting is on the 4th floor. The movements in the building are done only with an elevator as on the stairs there are renovation works. The elevator of this building when it descends, is allowed to reach a maximum speed of 4.5 m / s. The group is represented by 4 people whose average mass is 75 kg. The leader of the group pressed by mistake the button on the 8th floor and the members of the group found themselves on the 8th floor.
What should be the force on the cable to stop the elevator on the 4th floor where the meeting will take place?
The mass of an empty elevator is 1000 kg.g=9.80
Please write the answer in kN. (one decimal)
Find the value of moment
at point in the middle of section FH (point G),
at point in the middle of section CD,
at point in the middle of section HB
Please give the answer with one decimal.
The last day of FSA, students from AMZ wanted to find the mass of a Mercedes Benz
G-Class CLR G770,which usually used for routes from Red Bull Ring to FSA Campus, students managed to measure the gear pressure on each of the four tires and they found out that was 268 Kpa.
At the same time, some students were searching the BOM of Mercedes Benz
G-Class CLR G770 and they found that the touchable surface of each tire has an area of 265cm2. But they still didn't solve their problem, so it's up to you.
Please write the answer in kg and include one decimal
