The force in the figure keeps the 5.44 kg block and the pulleys in equilibrium. The pulleys have negligible mass and friction. Calculate the tension T in the upper cable. (Hint: When a cable wraps halfway around a pulley as here, the magnitude of its net force on the pulley is twice the tension in the cable.) 7 Numbe UnitSTN

In the figure, a cord runs around two massless, frictionless
pulleys. A canister with mass m = 42 kg hangs from one pulley, and
you exert a force F on the free end of the cord. (a) What must be
the magnitude of F if you are to lift the canister at a constant
speed? (b) To lift the canister by 4.0 cm, how far must you pull
the free end of the cord? During that lift, what is the...

The figure below shows two blocks connected to each other by a light cable that passes over a pulley with negligible friction. The block of mass m1 = 4.50 kg lies on a horizontal table with negligible friction, while the block of mass m2 = 11.2 kg hangs vertically. (a) What is the magnitude of the acceleration of each block (in m/s2)? (Here, a1 is the acceleration of m1,and a2 is the acceleration of m2.) a1 = m/s2 a2 =...

Block A in the figure has mass mA = 4.20 kg, and block B has mass mB = 2.40 kg. The coefficient of kinetic friction between block B and the horizontal plane is μk = 0.520. The inclined plane is frictionless and at angle θ = 34.0°. The pulley serves only to change the direction of the cord connecting the blocks. The cord has negligible mass. Find (a) the tension in the cord and (b) the magnitude of the acceleration...

Consider the system of connected masses and pulleys shown in the figure. The system is released from rest with the cable is rigid and under tension. The friction coefficients for the 60 kg mass are us = 0.25 and up = 0.20. Determine the acceleration of each body and tension T in the cable. Neglect the mass and friction of the pulleys. 60kB Moot 20 kg 30°

The system in the figure is in equilibrium. A concrete block of
mass 245 kg hangs from the end of the uniform strut of mass 38.5
kg. For angles ? = 26.5° and ? = 61.3°, find

(b) horizontal and (c)vertical
components of the force on the strut from the hinge.

For the next 7 questions, consider the system below. The large block has a mass of 45 kg (CG in center), with a width of 2 m and height of 1 m. The cable attaches to the large block at its corner as shown. The small block has a mass of 40 kg. Do NOT neglect the mass of the pulley. The pulley has a mass of 10 kg and a radius of 0.25.
