Answer:
the horizontal force acting on rod is - 25.909 N
veritical force is 25.48 N
Explanation:
Given data:
mass of rod is m 2.6 kg
length of rod is 1.5 m
Hinge distance from the wire is 0.70 m
Apply torque law about hinge
Tension in the wire is
![T = \frac{[\frac{1.5}{2} cos 28 ]2.6 \times 9.8}{0.70}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B%5B%5Cfrac%7B1.5%7D%7B2%7D%20cos%2028%20%5D2.6%20%5Ctimes%209.8%7D%7B0.70%7D)
= -25.909 N
the horizontal force acting on rod is
Fx = T
FX = - 25.909 N
vertical force is
Fy = mg
Answer:
A gas that exerts a pressure of 14 bar in a container with a volume of 312 mL will exert a pressure of 6.7 bar when transferred to a container with a volume of 652 mL.
Explanation:
1. 6.0 m
force/mass× acceleration is the equation
since the accelaration is unknown you would divide 180 by the mass of 30kg which is 6
2.A
Answer:
Technician B
Explanation:
A thermostat being stuck in an open position allows coolant to constantly circulate through the radiator which will cause a drop in the temperature of the engine. Hence, thermostat being stuck in an open position has nothing to do with burst upper radiator.
On the other hand, a radiator cap controls the pressure within the radiator which needs to be kept constant in order prevent overheating or damage to the radiator itself.
Therefore, technician B is correct.
