Question
static equilibrium
1. when a certain truck stands on a level roadway, its front wheels support 1.11 kN, and its rear wheels support 18.9 kN. if the front and rear axles are 3.66m apart, the horizontal distance between the rear axle and the center of gravity of the truck is approximately
a. 0.305m
b. 0.610m
c. 0.244m
e.0.203m
3. if you neglect the weight of the car , what is the maximum weight W that can be suspended from the car if the horizontal guy wire will break under a tension of 5.60 kN?
a. 4.00 kN
b. 5.60 kN
c.6.70 kN
d. 4.23 kN
e.3.00 kN
Explanation / Answer
1) e) 0.203 m
here net torque is zero.
18.9*10^3*x = 1.11*10^3*(3.66-x)
18.9*x = 4.0626 - 1.11*x
x = 4.0626/(18.9+1.11)
= 0.203 m from raer wheel
3)
b. 5.60 kN
