Q3. A truss is loaded as shown below. Determine: a) The zero-force members (without any calculations). (/5) b) The force in member DE, DF and GF using the method of sections. Indicate whether the member is in compression or tension. (/10) c) The force in member CD using the method of section. Indicate whether the member is in compression or tension. (/10) Take X to be the three last digits of your student number. You must replace X right away in your calculations, otherwise you will receive a mark of 0.
