Step by step solution

01

Part (a) Step 1 : Given information

A steel cable is lifting a girder and the girder is speeding up.

02

Part (a) Step 2 : Explanation

There are four interactions in below diagram can be seen.

There is the interaction between the steel cable and girder, interaction between girder and the surface, interaction between the earth and steel cable interaction between the earth and girder.

The interaction diagram is:

03

Part (a) Step 3 : Final answer

The interaction diagram is :

04

Part (b) Step 4 : Given information

A steel cable is lifting a girder and the girder is speeding up.

05

Part (b) Step 5 : Explanation

A system is defined as the space which consist all the constituent participating in the space.

Here the system consists of the steel cable and girder.

06

Part (b) Step 6 : Final answer

The system consists of the steel cable and girder.

07

Part (c) Step 7 : Given information

A steel cable is lifting a girder and the girder is speeding up.

08

Part (c) Step 8 : Explanation

T1andT2are the tension force acting on girder and cable respectively. There will be gravity force due to its weight which is acting opposite to the tension, and they are WCandWG.

The free body diagram is :

Part (c) Step 9 : Final answer

The free body diagram is :

FIGUREP7.39shows a block of mass m resting on a 20掳slope. The block has coefficients of friction渭s=0.80 and渭k=0.50 with the surface. It is connected via a massless string over a massless, frictionless pulley to a hanging block of mass 2.0kg.

a. What is the minimum mass m that will stick and not slip?

b. If this minimum mass is nudged ever so slightly, it will start being pulled up the incline. What acceleration will it have?

The cable cars in San Francisco are pulled along their tracks by an underground steel cable that moves along at 9.5mph.The cable is driven by large motors at a central power station and extends, via an intricate pulley arrangement, for several miles beneath the city streets. The length of a cable stretches by up to 100ftduring its lifetime. To keep the tension constant, the cable passes around a 1.5mdiameter 鈥渢ensioning pulley鈥� that rolls back and forth on rails, as shown inFIGURE100ft. A 2000kgblock is attached to the tensioning pulley鈥檚 cart, via a rope and pulley, and is suspended in a deep hole. What is the tension in the cable car鈥檚 cable?

A 3000kgmeteorite falls toward the earth. What is the magnitude of the earth鈥檚 acceleration just before impact? The earth鈥檚 mass is5.98脳1024kg.

A 70 kg tightrope walker stands at the center of a rope. The rope supports are 10 m apart and the rope sags 100 at each end. The tightrope walker crouches down, then leaps straight up with an acceleration of 8.0 m/s2 to catch a passing trapeze. What is the tension in the rope as he jumps?

A long, 1.0kgrope hangs from a support that breaks, causing the rope to fall, if the pull exceeds 40N. A student team has built a 2.0kgrobot 鈥渕ouse鈥� that runs up and down the rope. What maximum acceleration can the robot have鈥攂oth magnitude and direction鈥攚ithout the rope falling?
