Please do the last three questions (2, 3 and 4)! Thank you in advance! A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center. 1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left end. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs? 2- Now, a third child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum on the right side. What are the CW and CCW moment of the seesaw now? What is the net moment and direction? 3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?) 4- Now the fourth child leaves the other three children sitting on the plank. If the three children are sitting in the same potions as they did…

Fill in all blanks before submission. Round the answer to the nearest integer The figure shows a rod of length 6 ft and weight 100 lb hinged to the ground at point A. The rod rests on a stone in the shape of a sphere of radius 3ft. The center of the sphere O is located at a distance of 5 ft from point A. The normal reaction N between the sphere and the rod is lb. The horizontal component of the reaction at A is lb while the vertical component of the reaction at A is lb. 6 ft The magnitude of the reaction at A is lb. The angle of the reaction at A is 3 ft 0 5 ft
A dog is pulling on his lead at an angle of 39 degrees with a force of 50 Newtons. What is the force downward? Newtons. What is the force horizontally? Newtons. Note: You can type the trig in the answer box for all these problems. For example if the answer is 50cos(10), you can just type that into the answer box. To get inverse trig functions type arcsin, arccos or arctan.
PROBLEM 3: POWER AND EFFICIENCY PLEASE HELP ME WITH MY ASSIGNMENT - Solve the problems on a clean sheet of paper. Follow the Given-Required-Analysis-Solution-Summary of Answers format. Make sure to include all pertinent solutions. - Round your final answers to three (3) decimal places. For example, if you calculated an answer to be “9.80665” it should be expressed as “9.807”. At the instant shown, point P on the cable has a velocity vp = 12 m/s which is increasing at a rate of ap=6m/s2. Determine the power input of motor M at this instant if it operates with an efficiency of 0.8. The mass of block A is 50 kg.
A concrete block is at rest on an inclined plane that makes an angle of 37° with respect to the horizontal. If the concrete block weighs 206 lb, what is the frictional force between the block and the inclined surface? Round to 1 decimal place. Recall that, since the block is not moving, the frictional force that holds it in place is exactly the same size as the component of the weight parallel to the ramp but in the opposite direction. y Ff 37° 37° 206 lb Frictional force =
A team of professional thieves wants to knock down a castle wall using a primitive explosive. At theirheadquarters, they determine that the explosive has a mass of 40.0 kg and will break into three pieces: a 20.0 kgpiece will go exactly east, a 10.0 kg piece will go exactly south, and a 10.0 kg piece will go somewhere. Find thespeed and direction of the third piece of the explosive.
You are driving on the highway, and you come to a steep downhill section. As you roll down the hill, you take your foot off the gas pedal. You can ignore friction, but you can't ignore air resistance. Draw a free-body diagram of the car. Draw the force vectors with their tails at the dot. The orientation of your vectors will be graded. The exact length of your vectors will not be graded. 0 No elements selected w Select the elements from the list and add them to the canvas setting the appropriate attributes.

Inclined plane diagram: Also String 1 String 2 String 1 B C A The diagram above shows Carts B and C which roll without friction over an inclined plane. The plane is inclined at an angle of theta = 0 away from vertical, as shown in the diagram. Carts B and C are connected by an essentially massless string. Another massless string runs from Cart B over a massless and frictionless pulley to a hanging block, Block A.
