Name: Period: This bridge spans a 10ft wide creek. A 30lb downward force is located at the top center of the bridge.Calculate the load forces and the X and Y components of each member. Round to 2 decimal places for all forces. For each member, state whether in tension or compression. All force diagrams and triangles should be shown on the back of this page or an additional sheet. Bridge is symmetrical and static. Ay 58.00 - 10 30 lbs D 48.98 E How much force is Ay and Ey? Ay=________ lbs Fy= Can this problem be solved using the method of joints? circle- YES/NO lbs Fy 2j = m+ 3

Need the 2nd question solved please. the first one has been done

PLEASE ANSWER IT COMPLETELY. SHOW COMPLETE SOLUTION. FINAL ANSWER MUST BE IN 3 DECIMAL POINTS. DO NOT ROUND OFF INTERMEDIATE NUMBER.

Please solve it in a handwritten format with a free body diagram. Don't use chat gpt. (Diagram is mandatory) Mechanical engineering -

Simple Machines-Levers, Inclined Planes, and Pulleys Directions: Use the appropriate equation to answer the following questions. All answers should be recorded below or in your Engineering Design journal. Remember to show all work. A lever has an effort arm that is 5 meters long and a resistance (load) arm that is 3.5 meters long. How much effort is needed to lift a 100 Newton weight? 5K i). Draw the figure representing the problem ii). How much effort is needed to lift a 100 Newton weight? iii). What is the Actual Mechanical Advantage 1. 5m i) AOON 5-5m

Q1. As shown in the image below, the force acting on the box is F = (C · s²) Determine the work done by force F to the box when the box has displaced s = 1.7 m. Please pay attention: the numbers may change since they are randomized. Negative sign must be included if the work done is negative. Your answer must include 2 places after the decimal point, and proper Sl unit. N, where constant C = 6 and s is displacement in m. S F -

The 80-lb door has its center of gravity at G. (Figure 1) Figure 1 of 1 18 in. 24 in. 24 in. 18 in.

2. For this series of 4 questions, a man sits in the chair which is pin-connected to the 10-m frame BC. Frame BC rotates counterclockwise. Your final goal is to determine the magnitude of the support force N exerted by the chair on the man at the instant = 30°. But before that, you need to answer some other questions. Please pay attention: the numbers may change from problem to problem since they are randomized. 4) If at this instance he has a speed of 5.2 m/s, which is increasing at 0.8 m/s², and the man has a mass of 90 kg, determine the magnitude of the support force N exerted by the chair on the man at the instant = 30°. Your answer must include 2 places after the decimal point, and the proper unit. Take g = 9.81 m/s². C Your Answer: Answer 10 m 0 units B

Can anyone help me with this question
