An inhomogeneous rod is suspended and at rest in a horizontal position by two weightless cables, as shown in the figure below. The wire ropes form angles θ = 36.0 and φ = 53.1 degrees with the vertical. If the length L of the rod is 6.10 m, calculate the distance x from the left end of the rod to the center of mass.

Which of the following sentences are correct?
If a vehicle breaks down and fails to start for 2 min, it will be removed from the track and will not be allowed to re-enter the track.
The TSMS must be placed in a circular area of ≥50 mm radius placed on a high contrast background
A team must be able to separately disconnect at least one of the APPSs signal wire to check all functionalities.
All components and sensors must be positioned within the surface envelope or within the box defined in T 8.2.
A projectile, free of resistance and other frictions, is launched from a height h = 500m with a speed v0 downwards, forming an angle φ = 60o with the vertical. Find the range R of this shot if the body hits the ground t = 4s after launch. Also find the measure of the initial velocity v0 .
600 m, 130m/s
730 m, 210 m/s
730 m, 320 m/s
730 m , 180 m/s
A moving belt transports sand which is dropped vertically from a feeder at a rate of dM/dt. Calculate the required force that must act on the belt to keep the speed constant due to the additional load.
V/4*dM/dt
V/2*dM/dt
2V*dM/dt
V*dM/dt
Which of the following sentences are not correct?
Composite front hoop bracing structures and their attachments cannot be counted towards the front bulkhead support structures and vice-versa for the structural equivalency documentation.
The ready-to-drive mode must be left immediately when the shutdown circuit is opened.
The TSAL must not have any microcontrollers inside, because software control is not permitted.
Any harness that is fastened to the primary structure using brackets must use two 8 mm metric grade 8.8 or stronger fasteners
An open vessel of large diameter and height H filled with water lies stationary on a horizontal floor. At a distance h from the surface of the water we open a small hole, from where the water is ejected horizontally. Investigate the possibility of opening the hole at another height h′ so that the water jet erases the same range x. How much is this distance h′?
Any hole will give the same range
H' = H-h.
H' = H - 1/2*h.
There is only one height which can give you the legth x.
