Answer
given,
Assume radius of the disk be = 0.8 m
angular velocity of disk
ω = ( 5 t² + 2 ) r a d / s
magnitude of velocity and acceleration = ?
At the instant of time, t = 0.5 s
ω = ( 5 x (0.5)² + 2 ) r a d / s
ω = 3.25 r a d / s
α = 5 rad/s²
velocity
v = ω r
v = 3.25 x 0.8
v = 2.6 m/s
tangential acceleration
normal acceleration
magnitude of the acceleration
a = 9.35 m/s²
Answer:
B = 2.5 10⁸ Pa
Explanation:
The volume modulus is defined by
B =
The negative fate is for the module to be positive since the volume change is negative
It is not necessary to reduce the volumes to the SI system, since they are both in the same units
B = =
B = 2.5 10⁸ Pa
