Sample Problem 12.02 Balancing a leaning boom Balancing a leaning boom Figure 12-6a shows a safe (mass $M = 430$ kg) hanging by a rope (negligible mass) from a boom ($a = 1.9$ m and $b = 2.5$ m ) that consists of a uniform hinged beam ($m = 85$ kg) and horizontal cable (negligible mass).

A $1200.0 \mathrm{N}$ uniform boom is supported by a cable, as shown in Figure $8-22$. The boom is pivoted at the bot. tom, and a $2000.0 \mathrm{N}$ weight hangs from its top. Find the force applied by the supporting cable and the components of the reaction force on the bottom of the boom. (See Sample Problem 8 B.)
In order to raise a mass of $100 \mathrm{~kg}$ a man of mass $60 \mathrm{~kg}$ fastens a rope to it and passes the rope over a smooth pulley. He climbs the rope with acceleration $5 \mathrm{~g} / 4$ relative to the rope (sec Fig. 7.317). The tension in the rope is (take $g=10 \mathrm{~m} / \mathrm{s}^{2}$ ). a. $1432 \mathrm{~N}$ b. $928 \mathrm{~N}$ c. $1219 \mathrm{~N}$ d. $642 \mathrm{~N}$
The boom in the crane of Fig. 12.21 is free to pivot about point $P$ and is supported by the cable attached halfway along its $18-\mathrm{m}$ length. The cable passes over a pulley and is anchored at the back of the crane. The boom has mass $1700 \mathrm{kg}$ distributed uniformly along its length, and the mass hanging from the boom is 2200 kg. The boom makes a $50^{\circ}$ angle with the horizontal. Find the tension in the cable. (FIGURE CAN'T COPY)
