Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of ? = 64.0? with the floor and rope segment CD creates an angle ? with the horizontal. If both ropes BCA and CD can support a maximum tensile force Tmax = 675N , what is the maximum weight Wmax of the crate that the system can support? What is the angle required for equilibrium?

A 9.0 Kg box of oranges slides from rest down a frictionless incline from a height of 5.0 m. A constant frictional force, introduced at point A, brings the block to rest at point B, 19 m to right of point A. What is the velocity of the box just be..
Petrus takes a cold glass of cola from fridge. He puts 3 cubes of ice into it. He laeves the glass on a table in a warm room for 5 minutes. He notices that the ice cubes have become smaller. The outside of the glass is now wet. What is the reason ..
