Answer:
Explanation:
load = 4500lb lift height= 30 ft
time =15 s
velocity=
ft/s
velocity=2 ft/s
power = force
velocity
power=
power= 9000 lb ft/s
1 hp= 550 lb ft/s
power=
hp
Answer:
true
Explanation:
Creep is known as the time dependent deformation of structure due to constant load acting on the body.
Creep is generally seen at high temperature.
Due to creep the length of the structure increases which is not fit for serviceability purpose.
When time passes structure gain strength as the structure strength increases with time so creep tends to decrease.
When we talk about Creep rate for new structure the creep will be more than the old structure i.e. the creep rate decreases with time.
