0.25 m 25 kN B A 0.4 m E 0.2 m In the assembly shown points B and D are connected by double link members BD and points C and E are connected by a single link CE. Each of the three vertical links has an 8x 40-mm uniform rectangular cross section and each of the four pins has a 16-mm diameter. Member ABC has a 12x 50-mm uniform rectangular cross section. For the loading shown, determine 2) The force in link CE (kN) • (Positive if tension and Negative if compression)

All of the following are TRUE regarding levers EXCEPT O a lever can increase the effect of force application to a body O a lever can increase the speed with which a body can be moved O a lever can increase the distance through which a body can be moved in a given time O the effect a lever has is dependent upon the location of the fulcrum, resistance, and the force in relation to each other. O all of the above are true

The system shown consists of cable segments AD, BD, and CD knotted together at D. Force F acts at point D as shown. Determine the magnitude of the tensile forces in pounds in cable segments AD, BD, and CD. Tad- _______________ lb Tbd- _________________ lb Tcd- _________________ lb

A seesaw is a flat board that is balanced on a fulcrum (point of balance). When the weight at either end is equal, the seesaw is balanced and both ends are at the same height. When weight is added to either side, the balance will tilt in that direction. To prevent the balance from tipping, the location of the fulcrum must be moved to accommodate the difference in weights placed on each end. A playground equipment company wants to produce a seesaw that will be perfectly balanced when an adult and a child are on either end. The company estimates that an adult, on average, weighs four times as much as a child. The length of the seesaw is 10 feet. C A { 01 2 3 4 5 6 7 8 9 10
