4. A pick-up truck that has a mass of 2.5 metric tons pulls a trailer with a mass of 1 metricton. The engine of the truck has a pulling capacity of 5 kN. The horizontal drawbar usedto pull the trailer has a capacity of 600 N only, if exceeded, will disengage. If the full powerof the engine is used, will the horizontal draw bar disengage or not? Specify your answerif YES or NO. Explain why based on your computation.

The cart and its contents have a total mass of 4500 kg and a center of gravity at G as shown in Figure Q4. The coefficient of static friction between the wheels and the tracks is l = 0.4 when the wheels are locked. The normal forces acting on the wheels at (A and B) are independent as to whether the wheels are locked or not. Therefore, 10kN 0.9 m 0.15 m : 0.6 m 土 1.5 m Figure Q4: The cart.
The needle-nose pliers are used to either cut objects at location A or grip objects at location B. Compute (a) the cutting force at A and (b) the gripping force at B in terms of the applied force F.

Draw a free body diagram. Include the free body diagram and your calculations in your work that you submit after the quiz. R C A A pulley has a negligible mass (that means, the radius is not relevant). It is supported with a pin at the center (and is free to rotate). A rope goes over the pulley. Block A, which has a mass of 7.388 kg is connected to one side of the rope. On the other side, Block B, with a mass of 17.455 kg is connected. The system is released from rest. What is the speed of block B, after B has traveled 0.350 m? Please enter a positive value in m/s (but without units) regardless of the direction of the motion of B.
5. The figure below represents the anatomy of the lower limb when balanced on your toes and the body weight acts through the tibia. The Achilles Tendon makes an angle (0) of 8° with the vertical and for this foot x1 is 6.2 cm and x2 is 12.3 cm. Calf Muscle Tibia Achilles Tendon Calculate the tension (T) in the Achilles Tendon if a 70 kg man stands on the toes of both feet. Using the values in this example what is the mechanical advantage for this lever and describe what that means in terms of the efficiency of the lever.
A former student of mechanics wishes to weigh himself t has access only to a scale A with capacity limited to 110 lbs and a small 20- lb spring dynamometer B. With the rig shown he discovers that when he exerts a pull on the rope so that Bregisters 18 lb, the scale A reads 84 lb. What is his correct weight? Answer: Weight= lb
