Solution: P = 442.1 N 3m 50 kg

1. Using the example in the deadlift photo, draw a simplified free body diagram of the system. Add to your picture: FBb – Weight of the Barbell RBb – MA of BarbellFTr – Weight of the Trunk at segment COM RTr – MA of TrunkFTh – Weight of the Thigh at limb COM RTh – MA of ThighFm – Force of the Lower Back muscles Rm – MA of musclesFj – Joint reaction force on Lower Back

Need help on all questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.

Do not round off intermediate values when using them to solve subsequent values; however, they may be written up to 4 decimal places in the answer sheets. Final answers should be rounded off up to 4 DECIMAL PLACES. Box the final answers.

Statics, Find the force in members CD, CF, and FG of the truss and indicate whether the member is in Tension or Compression, given:P = 220 lbs, L1 = 4 ft, L2 = 6 ft(Use positive values to indicate Tension and negative values to indicate Compression)

Helping tags: Statics of rigid bodies, engineering math . . . WILL UPVOTE, just pls help me answer the question and show complete solution. Thank you!

All 4 pls
