Load shedding was implemented to save money. It also saves pollution. Load shedding is what electric utilities do when there is a huge demand for electricity that exceeds the generation available. The alternative is to have a brown-out where the voltage is reduced. It costs a lot to have generators standing by just in case there is a surge of demand‚ and the operators of those generators expect to be paid whether they run the generators or not. An alternative is if there is a large consumer

edProblems caused by load shedding FALIURE OF INDUSTRIES: The first problem which happened due to load shedding is the failure of industry in Pakistan .This effect badly on all types of industry. In mini industry there is no alternative source of electricity so when load shedding started these industries stop their work. In big industry although they have a source of electricity but if they produce electricity from their own source then its cost becomes very high

1. Characteristic Loads-Characteristics‚ Importance‚ Applications Actions By E.C. An action (F) is a force (load) applied to the structure (direct action ) or an imposed deformation ( indirect action ) ex. Temperature effects. Actions are classified: a) by variation in time permanent actions G ( self-weight of structure). b) by their spatial variations: fixed actions ( self weight ) variable actions Q wind loads/snow. free actions which results in different actions accidental actions

bodies. Some of the characteristics of our muscles are that they respond to stimuli‚ they are able to shorten in length‚ they stretch when they are pulled and they tend to return to their original shape after contracting or extending them. Muscle contractions occur when our nervous system sends a signal via the neuromuscular junctions the signal arrives at the end bulb‚ the vesicles release acetylcholine and diffuse across the neuromuscular cleft. The transmitter molecules fill receptor sites in the

Albert is riding his scooter at a velocity of 80 km/h when he sees an old woman crossing the road 45 m away. He immediately steps hard on the brakes to get the maximum acceleration of 7.5 m/square second. how far will he go before stopping? Will he hit the old woman? 3. the time a male bungee jumper if

Regarding Figure 1‚ the regular heartbeat and contraction force of the toad was identified to demonstrate the difference between atrial contractions and ventricular contractions in a normal environment. In cardiac‚ skeletal‚ and some smooth muscle tissue‚ contraction occurs through a spectacle known as excitation contraction coupling (Freeman et al.‚ 2014). This process converts electrical stimulus from the neurons into a mechanical
