H7-4: For the system below, find the force F required to start C moving upward. Block B has a weight of 25 N and block C has a weight of 120 N. The static coefficient of friction is as following: 0.18 between A and B 0.15 between B and C 0.25 between C and the wall. 15°
QUESTION 5 (100 marks) (a) A crane is to be used to lift materials at a construction site. The crane is composed of a vertical mast 60 m high, a horizontal jib (B-D) 20 m long and a counter-jib (A-B) 4 m long. The combined weight of the counter-jib plus the counterweight provides a load of 18,000 N at point A. The weight of the jib provides a load of 5,200 N at point c. Note: not to scale 20m...
(a) What is the expression for the magnitude of the force F required to accelerate an elevator of mass m upward starting from rest to a height H to a final speed of V(f)? (b) What is the value of the force if m=1800 kg, h=120 m, and v(f)=16m/s?
