Un corps solide () de masse = 5 est en équilibre sur un plan incliné d’un angle par rapport à l’horizontale (voir figure).
1- Sachant que la force ⃗ exercée par le plan incliné sur le corps compense le poids ⃗ de ce corps :
1.1- Resprésenter sur le schéma de la figure la force ⃗ à l’échelle 1 → 20 .
1.2- Le contact entre le corps () et le plan incliné est-il avec ou sans frottement ?justifier.
2- L’intensité de la force pressante exercée sur la surface du plan incliné par le corps () représente 57.2%
du poids de ce dernier.
2.1- Représenter la force sur le schéma à la meme échelle que précédement.
2.2- Déterminer la valeur de la pression à la surface du contact.
Données : = 9.8.−1
, Aire du contact corps-plan incliné = 402
.
SVP pouvez vous m'aider avec l'explication
Pardon pour les fotes d'orthographes

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
