Answer:
c. Both Technician A and Technician B
Explanation:
It is true that the clutch slippage can be diagnosed with vehicle stopped parking brake applied, placing the transmission in 4th gear, and slowly releasing the clutch pedal to see if it stalls the engine. Hence techician A is correct.
Moreover, excessive slipping clutch can cause friction surface warpage ( being bent or twisted out of shape) and hot spot( heat energy from the friction.
Therefore, both technician A and B are correct.
Answer:
Explanation:
When beam is balanced and not rotating with Suki standing on it , let reaction force on the supports be R₁ and R₂. Then
R₁ +R₂ = 336 + 590
= 929
Now the moment beam begins to tip , reaction on distant support R₁ = 0
only R₂ will exists on the support near to Suki.
Taking torque about this support of weight of beam acting from the middle point and weight of suki of 590N ,who is x distance from the support towards the other end.
336 x 1.5 = 590 x
x = .85 m
ie , from second support , Suki can not go beyond a distance of .85 m towards the second end.
The point with the greatest potential energy is B.
The potential energy of an object is depends on the relative distance between the object and the ground and its mass. The higher the object is from the ground the greater the potential energy posses.
Potential energy (P.E) = mgh
Where m is the mass, g is the gravity and h is the height from the ground to where the object is.
Since the mass and gravity is constant in this case, only the height will determine the point with the greatest P.E and that point is B.
I am pretty sure the answer would be a
The momentum if the mass is 1.5kg and the velocity is 4 m/s is 6kg
