Engineering Materials Msc. Shaymaa Mahmood Introduction to Eng. Materials : Since the earliest days of the evolution of mankind ‚ the main distinguishing features between human begins and other mammals has been the ability to use and develop materials to satisfy our human requirements. Nowadays we use many types of materials‚ fashioned in many different ways‚ to satisfy our requirements for housing‚ heating‚ furniture‚ clothes‚ transportation‚ entertainment‚ medical care‚ defense and all the

Impregnation of rubber wood has been carried out under different conditions by using styrene as grafting monomer and glycidyl methacrylate (GMA) as crosslinker. Properties such as dimensional stability‚ water absorption‚ hardness‚ tensile strength‚ flexural strength‚ etc of the impregnated wood have been checked and found to be improved by incorporation of GMA as the crosslinker with styrene. The polymerimpregnated wood has also been characterized by FTIR spectroscopy and DSC. Keywords. 1. Wood;

Circuit training is a workout routine that combines cardiovascular fitness and resistance training. Circuit training is an excellent way to simultaneously improve mobility‚ strength and stamina. The circuit training format is a method of physical conditioning in which one utilizes a group of 6 to 10 strength exercises that are completed one exercise after another. Each exercise is performed for a specified number of repetitions or for a prescribed time period before moving on to the next exercise

replace cold rolled steel as purlins or girts. If GRFP is utilized‚ the portal frame section can be design to consume less steel because GFRP is light weight. Since it has a very high strength to weight ratio‚ being light weight‚ GFRP does not make it loose its strength. Regardless‚ this material still possesses less strength compared to steel. This material is also environment and corrosion resistance‚ so when used as purlins or girts member‚ it will not rust when get in contact with rain water. The energy

program uses STIFF LEG DEAD LIFTS! It does not use dead lifts! There are TWO warm-up sets and TWO work sets making FOUR sets per exercise in total! You will start with EIGHT reps of your ten rep max weight! Not ten. This program splits gains between strength and size. You increase the reps every week‚ you do not increase the weights until completing a 5 week cycle. STARTING WEIGHT What weight should I start with? The correct starting weight is about a 10 rep max (75% of your 1 rep maximum). If

the properties of bioplastic made from agar-agar‚ a species of seaweed‚ and potato starch. Through the study‚ the researchers attempted to discover which bioplastic would be more viable for both industrial and personal use‚ in terms of its tensile strength‚ flexibility‚ water resistance and mouldability. In the procedure‚ for the first set-up‚ vinegar‚ glycerol and water were mixed in a bowl together with potato starch. The second set-up had a similar mixture‚ although instead of adding
