How do I calculate the expected voltage at the base, emitter and collector?

A tractive effort of 3kN drives a 5 ton truck from rest up an inclince of 1 in 40. If the tractive resistance is constant at 380N and the tractive effort is parralel to the plane of the incline, use the method of conservation of energy to calculate the speed of the trcuk after it has traveled 250m up the incline.

PLEASE ANSWER ACCORDINGLY this is the third time im reposting because answers are either wrong or irrelevant

Clearly show the following values:

Ek=?

Ep=?

ETR=?

ETE=?

Energy equation=?

v=?

A metal block starts from rest and slides 12 m down a chute that is inclined at 40° to the horizontal. It then continues to slide along a horizontal length of the chute and eventually comes to rest. If μ = 0,2 between the chute and the block, calculate the horizontal length of the chute. Use conservation of energy to solve this question.

What is the Moment of a Couple?

The center rod CD of the assembly shown in the figure is heated from T₁ = 30^oC to T₂ = 180^oC using electrical resistance heating. The two end rods AB and EF are heated from T₁ = 30^oC to  T₂ = 50^oC. At the lower temperature T₁, the gap between C and the rigid bar is 0.7 mm. Rods AB and EF are made of steel and each have a cross-sectional area of 125 mm². CD is made of aluminum and has a cross-sectional area of 375 mm². E_Steel = 200 GPa, E_Aluminum = 70 GPa,    α_steel = 12x10^-6/^oC, α_Aluminum = 23 x10^-6 /^oC.

Calculate the force and the stress in rods AB, EF and CD caused by the increase in temperature.
