Answer:2.737 kN
Explanation:
Given
mass of log(m)=205 kg
ramp inclination
coefficient of kinetic friction between log and ramp is (
)=0.9
log has an acceleration of 0.8 m/s^2
Let T be the tension in the rope

Where
=Sin component of weight
(Where N is Normal reaction)


sin30=0.5
cos30=0.866


Answer:
The right answer is option C
Answer:

Explanation:
As we know that the radius of the circular motion is given as

time period of the motion is given as

now we know that it is moving with uniform speed
so it is given as

now plug in all data


Answer:
t = 0.2845Nm (rounded to 4 decimal places)
Explanation:
The disk rotates at a distance of an arc length of 28cm
Arc length = radius × central angle × π/180
28cm = 10cm × central angle × π/180
Central angle =
× 180/π ≈ 160.4°
Torque (t) = rFsin(central angle) , where F is the applied force
Radius in meters = 10/100 = 0.1m
t = 0.1m × 16N × sin160.4°
t = 0.2845Nm (rounded to 4 decimal places)
Answer is 12 milesBecause yeah
