In the figure the body hanging from three strings a, b and c. If its mass is m = 2kg, determine the tension force in the string b. (g = 10m / s2)
Two blocks each of mass m are fastened to the top of an elevator as in the figure below. The elevator has an upward acceleration a. The strings have negligible mass.
(a) Find the tensions T1 and T2 in the upper and lower strings in terms of m, a, and g.
T1
=
T2
=
(b) Compare the two tensions and determine which string would break first if a is made sufficient large.
A block of mass m1 on a rough, horizontal surface is connected to a second mass m; by a light cord over a light frictionless pulley as shown in the figure. ('Light' means that we can neglect the mass of the cord and the mass of the pulley.) A force of magnitude Fis applied to the mass m4 as shown, such that m1 moves to the right. The coefficient of kinetic friction between m1 and the surface is p. Derive a formula for the acceleration of the masses. [Serway 5th ed., pg.135, Fig 5.14]
